Digital occlusal analysis of the impact of natural dentition and different types of rehabilitation on the occlusal force variations: systematic review and meta-analysis Ponsekar Abraham Anandapandian, Fathima Banu Raza, Pradeep Kumar AR, Sridevi Krishnamoorthy, V. Ashok, V. Anand kumar, Vijayalakshmi P Journal of Oral Biology and Craniofacial Research, 2025 Statement of problem: Dental restorations reduce occlusal force through a compensatory feedback mechanism. Thus, the type of restoration used during rehabilitation plays a vital role in altering occlusal force and contact area. The effects of factors such as the remaining dentition, occlusal contact area, and different types of rehabilitation on occlusal force need further exploration. Aim: Evaluate the evidence of occlusal contact areas and various rehabilitation methods on influencing the occlusal force assessed using digital occlusal analyzers.Materials & Method: The protocol followed the Cochrane standards for systematic reviews and was registered in PROSPERO (CRD42024623551). The literature search used the Population, Exposure, Comparator, Outcome, Study Design (PECOS) strategy. Database for searched until December 2024. Randomized controlled trial, observational studies including cohort, case-control, and cross-sectional studies that investigated the relationship of occlusal force with occlusal contact area, masticatory force, occlusal time, and number of remaining natural dentition using Dental Prescale or T scan. Results: = 46 %) in the quantitatively assessed studies. The mean difference of occlusal force with rehabilitation was -10.02[95 % C.I(13.03, -7.03)] depicting prosthesis improved the occlusal force. However, qualitative analysis revealed that the occlusal force with prosthesis was lesser than the natural dentition quadrant. Conclusion: Occlusal force was increased with rehabilitation compared to the edentulous site, however, the amount of force established in a complete set of natural dentitions was more than the rehabilitated site. The location of teeth in the arch, and the number of remaining dentitions played a role in occlusal force.
Antifungal efficacy of chitosan-mediated fenugreek nanocomposite incorporated in tissue conditioner Mohika Damle, Ponsekar Abraham Anandapandian, B. Eswaran, Swapnaneel Pradhan, Silvin Joe C J, Shreyas Dhumke Journal of Oral Biology and Craniofacial Research, 2025 Introduction: being a primary culprit. Tissue conditioners, used to reline ill-fitting dentures, can temporarily alleviate discomfort but are prone to microbial colonization. To address this, researchers have explored incorporating antifungal agents directly into tissue conditioners. Nanoparticles, particularly green-synthesized ones derived from fenugreek, have shown significant antifungal efficacy. Combining fenugreek extract with chitosan, can further improve antifungal outcomes due to its excellent drug delivery, mucoadhesive properties, and bioavailability Aim: To synthesize Chitosan mediated Fenugreek nanocomposite (1.5 %,2 %,2.5 % by weight concentrations) and evaluate its antifungal efficacy on heat cure denture base relined with tissue conditioner mixed with nanocomposite by assessing fungal colony formation after 1st day, 1st week and 2nd week. Methodology: After synthesizing chitosan mediated fenugreek Nanocomposite, its characterization was performed using SEM, FTIR analysis and UV-Vis spectroscopy. Heat cure denture base discs coated with tissue conditioner-nanocomposite mixture were used to transfer fungal cultures onto Rose Bengal agar to assess colony formation. Results and discussion: Chitosan-fenugreek nanoparticles were synthesized using the ionic gelation method, with fenugreek extract used for green synthesis. Kruskal-Wallis test showed significant effects over time, with 2.5 % group showing lowest fungal growth at 521 CFU/mL, followed by 2 % group at 587 CFU/mL, while the 1.5 % nanocomposite group still displayed considerable fungal growth. Conclusion: Incorporating chitosan-mediated fenugreek nanocomposite into denture tissue conditioners offers a promising approach to reducing Candidal growth, potentially improving oral health outcomes for denture wearers.
Automated Analysis of Tooth Anatomy and Pathological Conditions from Orthopantomogram using Deep Neural Networks Tuhina Sheryl Abraham, Vijay Jeyakumar, Gurucharan Marthi Krishna Kumar, Ponsekar Abraham Anandapandian IETE Journal of Research, 2024 This research project aims to automate the identification, labeling, and counting of teeth, as well as the classification of abnormalities and detection of caries in dental X-rays, specifically orthopantomograms (OPGs). It involves several deep neural networks and learning algorithms. The first module uses semantic segmentation with a U-net model to create masks for tooth detection, which are then refined with the YOLOv3 detector, achieving 80% accuracy. Canonical correlation analysis (CCA) helps find tooth midpoints and count the total number of teeth. The second module classifies abnormalities and pathologies using transfer learning with the Inceptionv3 model, yielding moderate accuracy. Caries detection is performed with thresholding and segmentation. The third module detects three treated pathologies—root canal treatments, crowns, and implants—using Faster RCNN and Inceptionv3, showing fair accuracy. Overall, the automated approach demonstrates promising results for enhancing X-ray image interpretation and diagnosing oral diseases.
Osteogenic potential of laser modified and conditioned titanium zirconium surfaces PDavid Charles, PonsekarAbraham Anandapandian, Shila Samuel Journal of Indian Prosthodontist Society, 2016 Statement of Problem: The osseointegration of dental implant is related to their composition and surface treatment. Titanium zirconium (TiZr) has been introduced as an alternative to the commercially pure titanium and its alloys as dental implant material, which is attributed to its superior mechanical and biological properties. Surface treatments of TiZr have been introduced to enhance their osseointegration ability; however, reliable, easy to use surface modification technique has not been established. Purpose: The purpose of this study was to evaluate and compare the effect of neodymium-doped yttrium aluminum garnet (Nd-YAG) laser surface treatment of TiZr implant alloy on their osteogenic potential. Materials and Methods: Twenty disc-shaped samples of 5 mm diameter and 2 mm height were milled from the TiZr alloy ingot. The polished discs were ultrasonically cleaned in distilled water. Ten samples each were randomly selected as Group A control samples and Group B consisted of Nd-YAG laser surface etched and conditioned test samples. These were evaluated for cellular response. Cellular adhesion and proliferation were quantified, and the results were statistically analyzed using nonparametric analysis. Cellular morphology was observed using electron and epiflurosence microscopy. Results: Nd-YAG laser surface modified and conditioned TiZr samples increased the osteogenic potential. Conclusion: Nd-YAG laser surface modification of TiZr, improves the cellular activity, surface roughness, and wettability, thereby increasing the osteogenic potential.
Prosthodontic and surgical management of anophthalmia: A case report P. Satheesh Simha Reddy, Murugesan, Ponsekar Abraham, Vasantha Kumar Journal of Indian Prosthodontist Society, 2014 True Anophthalmos is an extremely rare condition and can cause psychological problems due to not only the absence of an eye but also from the disfigurement of the orbital socket and the eyelids. The present case shows the multidisciplinary approach in the treatment of a patient with anophthalmos. He needed an ocular plastic surgery for correct prosthesis insertion. The disfigurement caused by the loss of ocular content when restored with prosthesis maintains the facial symmetry there by improves the esthetics as well as anatomic and physiological function.
A positional analyzer for measuring centric slide Anandapandian Ponsekar Abraham, Padmanabhan Thallam Veeravalli Journal of Indian Prosthodontist Society, 2012 Centric relation (CR) has been considered mainly as a position posterior to habitual occlusion or maximum intercuspation (MI). Awareness of the tooth contacts relationship in centric relation position of the mandible and diagnosing the case from this position is essential to consistently select treatment plans that will allow to treat to or very near to centric relation occlusion. Centric slide and other occlusal relationships are conceived of as positions, which can be studied in three dimensions. Clinically, the difference between the two occlusal positions namely CR and MI (centric slide) can easily be determined, but for a more precise evaluation of its length and directions, an occlusal analysis on articulator mounted casts is necessary. Study was under taken on the mounted casts of ten subjects on a semi adjustable articulator to which a stylus and recording table was devised and attached for measurement of CR-MI slide in the three planes namely anterior-posterior, medio-lateral and superior-inferior. It was found that there was a displacement from CR to MI (centric slide) in all the three planes and numerically the mean slide was 0.688 ± 0.623, 0.261 ± 0.627 and 0.127 ± 0.541 mm in the antero-posterior, medio- lateral and superior-inferior directions respectively. The stylus and table attachment may be an accurate indirect method to measure positional changes of the condyle in 3D.
The effect of implant design on the stress distribution in a three-unit implant-supported distal cantilever fixed partial denture: A three-dimensional finite-element analysis PonsekarAbraham Anandapandian, Pradeep Koka, Abhijita Mohapatra, K Murugesan, M Vasanthakumar Indian Journal of Dental Research, 2012 CONTEXT Implant design influences the stress distribution in an implant-supported distal cantilever fixed partial denture and supporting bone tissue. AIM The purpose of this study was to investigate the effect of implant design on the stress distribution in the framework, implant, and surrounding bone, using a three-dimensional finite-element analysis. MATERIALS AND METHODS A three-dimensional finite-element model of a mandibular section of bone with implants placed in the first and second premolar region was created to support a distal cantilever fixed partial denture. A one-piece and two-piece implant and its suprastructure were simulated into wire frame models using Pro engineer (Pro E) program. Four models were created in this study. RESULTS Comparative analysis of all models showed that the maximum stress overall was in the cervical portion of the secondary abutment. When used in combination, the maximum stress was when the two-piece implant was used as secondary abutment. The one-piece implant showed less stress compared to its counterpart when used as secondary abutment. The maximum stress distribution in the bone was around the neck region of the secondary implant. CONCLUSION Within the limitations of this study, it can be concluded that stress distribution is better in a one-piece implant design when compared with the two-piece implant design, with stress concentration being more at the junction of the abutment and the implant fixture in the two-piece implant. When implants are used as abutments (either primary or secondary), irrespective of their position and design, the secondary implant shows the maximum amount of stresses.
An invitro analysis of elemental release and cytotoxicity of recast nickel-chromium dental casting alloys Nagam Raja Reddy, Anandapandian Ponsekar Abraham, Krishnan Murugesan, Vasanthakumar Matsa Journal of Indian Prosthodontist Society, 2011 Recasting of the casting alloys affects the composition and elemental release which may have cytotoxic effect different from the pure alloy in the surrounding tissues. An Invitro study was conducted to investigate the elemental release and their cytotoxic effects from commercially available Ni-Cr dental casting alloys, commonly used for fabricating fixed partial dentures. Three Ni-Cr alloys [Wiron 99(A), Ceramet (B), and Hi Nickel CB (C)] were tested. Alloy specimens (disks 3 × 5 mm) were casted and grouped as follows: Group I (A(1)/B(1)/C(1)): 100% pure alloy; Group II (A(2)/B(2)/C(2)): 50% new with 50% recast; and Group III (A(3)/B(3)/C(3)): 100% recast. Disks of each alloy type from each group were transferred to Dulbecco's modified eagle medium and left for 3 days at 37°C in an atmosphere of 5% CO(2). Ni, Cr, Co, Cu and Mo elemental release from metal alloys into culture medium was investigated using Inductively Coupled Plasma Mass Spectrometry. Cytotoxicity was tested using mouse fibroblast cells and MTT Assay. Controls consisted of 6 wells containing cells with no alloy specimens. Data were analyzed by two-way analysis of variance followed by t-test. The total amount of elements released in parts per billion for various casting groups were Group I, A(1)-6.572, B(1)-6.732, C(1)-8.407; Group II, A(2)-22.046, B(2)-26.450, C(2)-29.189; Group III, A(3)-84.554, B(3)-88.359, C(3)-92.264. More amounts of elements were released in Hi Nickel CB than Ceramet and Wiron 99 in all the three test groups. Percentage of viable cells from MTT analysis were Group I, A(1)-62.342, B(1)-61.322 C(1)-60.593, Group II, A(2)-58.699, B(2)-56.494, C(2)-52.688, Group III, A(3)-53.101, B(3)-52.195, C(3)-47.586. The viable cells present in the culture media were more in Wiron 99 than Ceramet and Hi Nickel CB. Elemental release increased with amount of recast alloy. Amongst the three alloys tested Hi Nickel CB had significantly higher elements released compared to Ceramet and Wiron 99 in 100% pure alloys, 50% recast and 100% recast alloys. Wiron 99 showed least element release in 100% pure alloy, 50% recast and 100% recast specimens. 100% pure alloys of all three alloys are less cytotoxic, but their cytotoxicity is more on 50% and 100% re-casted alloys. Out of all three variations of casting Wiron 99 was least cytotoxic, followed by Ceramet and Hi Nickel CB. Recasting of alloys significantly increased the elements released and their cytotoxicity.
Telescopic overdenture supported by a combination of tooth and an implant: A clinical report Ponsekar A. Abraham, Pradeep Koka, K. Murugesan, M. Vasanthakumar Journal of Indian Prosthodontist Society, 2010 The conventional modality of treatment of partial edentulousness with reduced number of teeth was to render them complete edentulous and provide them complete denture or an overdenture with support of few remaining teeth. The goal of maintenance of roots are to prevent alveolar bone resorption, provide better load transmission, maintain sensory feedback and achieve better stability of denture with emphasis on psychological aspect of not being completely edentulous. Over the recent past titanium dental implants have been successfully used as tooth replacement with predictable results. A combination of tooth and implant support is well documented for fixed partial dentures but rarely for overdentures. This clinical report aims at evaluation of tooth root and implant supported mandibular overdenture treatment with telescopic coping.
