Effect of Ultraviolet Photofunctionalization of Titanium Dental Implants on the Stability, Osseointegration Speed and Crestal Bone Loss in Controlled Diabetic Patients: A Split Mouth Randomized Clinical Trial D. Murali Krishna, Sruthima NVS Gottumukkala, M. Satya Narayana Raju, Gautami S. Penmetsa, KSV Ramesh, P. Mohan Kumar, VNV Satya Valli, Bhavya Manchala Journal of Oral Implantology, 2025 Our objective was to evaluate and compare the effects of UV photofunctionalized (UVP) dental implants on implant stability, osseointegration, and radiographical bone changes with non-UV photofunctionalized (NUVP) dental implants placed in controlled diabetics. Participants were selected using stratified random sampling to ensure proportional representation of age groups, gender, and other relevant subgroups within the controlled diabetic population. The sites were randomly allocated into UVP and NUVP groups. In the UVP group, implants were photofunctionalized in a UV activator for 20 seconds before implant placement. Crestal bone changes were measured at 3- and 9-months postimplant placement. Descriptive statistics and paired t-tests were done to analyze intragroup and intergroup comparison study data. Implant stability and osseointegration were assessed using implant stability quotient (ISQ) and osseointegration index (OSI) immediately after implant placement and 3 months postplacement. Intragroup comparison of ISQ showed significantly higher ISQ (P = <.029) in the UVP group (4.40 ± 1.89) compared with the NUVP group (2.60 ± 1.17). The mean change in implant stability from baseline to 3 months was also significantly higher (P = .29) in the UVP group (4.4 ± 1.89) compared with the NUVP group (2.6 ± 1.17). A significantly higher mean OSI (P = .032) was noted in the UVP group (1.42 ± 0.62) compared with the NUVP group (0.84 ± 0.39). On comparison of mean crestal bone changes on the distal aspect, significantly higher mean bone loss (P = .003) was noted at 9 months in the NUVP group (0.64 ± 0.18) compared with the UVP group (0.35 ± 0.08). The UVP group showed greater benefits in enhanced secondary stability, higher OSI, and less crestal bone loss compared with the NUVP group in controlled diabetic patients.
Evaluation of Stability and Survival Rates of Short vs Standard Implants in Posterior Mandible: A Prospective Clinical Trial Gautami S Penmetsa, Konathala SV Ramesh, Lahari Karuturi, Mantena Satyanarayana Raju, Sruthima NVS Gottumukkala, Mohan KP, Inti Srividya World Journal of Dentistry, 2025 surpassed by the replacement of partially edentulous arches with short-term implants, thereby increasing the morbidity postoperatively and reducing the risk of complications as well.So, as an alternative to these surgical procedures, short implants have been developed to replace natural teeth in atrophic ridges. 1,5n the available implant literature, as of today, various authors have defined short dental implants, as per their criteria, wherein some consider 10 mm as short, while others consider <6 mm as short. 1,6 IntroductIonDental implants have emerged as the most predictable means of replacing lost teeth, with the primary goal of oral rehabilitation to improve the patient's quality of life, thereby enhancing the functions and esthetics of the stomatognathic system.Edentulism in the posterior mandible often limits patients' ability to perform daily routines and also plays a significant role in their functional activity. 1Although many treatment modalities, such as fixed partial dentures and removable partial dentures, have existed since time immemorial in dentistry, implants, which are a much recent innovation, do play a significant role in replacing natural teeth because of their high survival rates, thereby ensuring enhanced function and psychological comfort to the patient. [2][3]3][4] Following extraction, the bony socket usually undergoes many dimensional changes.These horizontal and vertical changes in bone urge the clinicians in routine practice to rely on several surgical techniques, such as GBR (guided bone regeneration), ridge augmentation procedures, and nerve transposition, in order to attain adequate bone volume so that standard implants can be placed. 1Moreover, these surgical procedures are not only technically sensitive but also subjected to postoperative complications, such as pain in the surgical site, graft resorption, and neurosensory disturbances, thereby affecting the compliance of the patient. 5ugmentation of bone vertically, which is usually associated with higher financial costs and prolonged treatment time, is 1,2,4-
Precision implant placement: A novel approach using dynamic navigation system-guided alveolar ridge splitting M. Satyanarayana Raju, Sruthima N. V. S. Gottumukkala, Koyya Sesha Sai Rakshitha, M. A. K. V. Raju Journal of Indian Prosthodontic Society, 2025 Conventional alveolar ridge splitting (ARS) technique involves a significant risk which may prove problematic. This case report presents the first documented application of dynamic navigation system (DNS)-guided ARS, demonstrating a precise approach to implant placement in a challenging anatomical scenario. A 37-year-old partially edentulous patient presented with missing mandibular posterior teeth. Clinical examination revealed a deficient alveolar ridge. Cone-beam computed tomography evaluation showed a Siebert’s Class I resorbed ridge with 2.5 mm width and bone density ranging from 870 to 1040 Hounsfield Units in the #46 and #47 regions. Creating and designing three-dimensional virtual guide slits and implant planning using DNS were done in patient with insufficient bone width in the mandibular molar region. Piezoelectric ARS, osteotomy preparation with implant placement was done. 0.70 and 0.26 mm deviations at #46 and 0.50 and 0.01 mm deviations at #47 were observed at implant entry and implant apex, respectively. The angular deviations were optimal. ARS using real-time navigation appears to be an efficient and promising technique.
Comparative evaluation of accuracy between dynamic navigation and freehand method during orthodontic implant placement: a split-mouth study Mohammed Farheen, Manda Anoosha, Mantena Satyanarayana Raju, CV Padmapriya, Datla Praveen Kumar Varma, Velagala Sai Keerthi Angle Orthodontist, 2025 Objectives To assess and compare the accuracy of infrazygomatic crest screws (IZC) placed with and without a dynamic navigation system. Materials and Methods Preoperative cone-beam computed tomography (CBCT) and intraoral scan of the maxillary arch were obtained for 12 patients requiring therapeutic first premolar extraction after leveling and alignment. Virtual planning of the final IZC screw position on both sides was done using Evalunav software. Maxillary left and right arches for each patient were randomized into experimental and control sides. A 12 × 2 mm dimension IZC screw was positioned with and without use of a dynamic navigation system randomly on either side. A postoperative CBCT was taken immediately to assess the final screw position. Preoperative and postoperative CBCTs were compared for deviation in the entry point, apical point, and angular point for experimental and control sides. Mean value deviations obtained were subjected to statistical analysis using SPSS 20.0 to describe the data. Results Paired t-tests were used to analyze the comparisons. Dynamic navigation showed a statistically significant difference in entry point and angular point compared to the freehand approach during implant placement. Conclusions IZC screws implanted with the dynamic navigation system offered better control with less deviation and greater accuracy in all three planes of space. However, further studies are necessary to determine the stability and anchor value of implants placed with a dynamic navigation system.
Peri-implant mucosal enhancement using leukocyte platelet rich fibrin under Sohn's poncho technique: A randomized controlled clinical trial B. Bharghavi Patnaik, Gautami S. Penmetsa, M. Satyanarayana Raju, N. Haripriya, Dinesh Gera, KSV Ramesh Clinical Advances in Periodontics, 2024 BackgroundA biological seal that protects the implant from any biological or external impingement is created by the supracrestal attached tissues. Sohn's poncho technique is a technique that utilizes a healing abutment at the implant site to stabilize the platelet rich fibrin (PRF) membrane. Thus, the aim of this study is to evaluate the efficacy of Sohn's poncho technique used for placement of leukocyte PRF (L‐PRF) membrane in improving the peri‐implant mucosal thickness and width of keratinized mucosa as well as in the acceleration of healing process compared to the peri‐implant mucosa surrounding healing abutments placed without the L‐PRF membrane.MethodsA split mouth randomized controlled clinical trial was designed in which implants were placed in the mandibular posterior region. Healing abutment is placed along with the L‐PRF membrane at the test site using Sohn's poncho technique and at control site conventional healing abutment placement was done at second stage. The thickness of peri‐implant mucosa as primary outcome and the Width of keratinized tissue and healing as secondary outcomes were measured and assessed at various time intervals.ResultsStatistically significant difference was seen in inter‐group analysis when peri‐implant mucosal thickness (3.8 ± 0.4 mm vs. 2.3 ± 0.4 mm) and width of keratinized mucosa (3.6 ± 0.6 mm vs. 2.7 ± 0.3 mm) in test and control groups respectively and intragroup analysis of test and control groups at 4 weeks and 6 weeks’ time points. The control group showed faster healing when compared to the test group.ConclusionSohn's poncho technique in combination with L‐PRF has the potential to improve the thickness of peri‐implant mucosa and the width of keratinized mucosa around implants.

Penmetsa, Mantena Satyanarayana Raju, Konathala Santosh Venkata Ramesh, Pasupuleti Mohan Kumar, Sathya valli Veluri Journal of Oral Medicine and Oral Surgery, 2024 Introduction: To retrospectively assess the mesio-distal angular deviation/inclination of single implants restored in the posterior edentulous arches and evaluate the effect of angular deviations on the early bone loss after 12 months of functional implant loading. Materials and methods: This retrospective Cone beam computed tomography (CBCT) analysis assessed 60 single implants including 36 axially placed (AX Group) and 24 non-axially (NAX Group) placed implants of dimension 4.2 × 10 mm. Marginal bone loss (Mesial, Distal) was assessed at 1 year post implant loading in both maxillary and mandibular implants. Independent sample t-test was done for intergroup comparison and paired t-test for intragroup comparisons. Results: Mean MBL was significantly greater (P-0.02) in NAX group compared to AX group on both mesial and distal sides. Maxillary implants showed greater MBL (3.17 ± 1.33, 2.99 ± 1.63 on mesial and distal sides respectively) compared to mandibular implants (1.86 ± 0.53, 2.29 ± 0.90 on mesial and distal sides respectively). Conclusion: Greater mean MBL during first year of functional loading in NAX group and maxillary implants was observed with minimal post-operative complications and good survival rate in both groups.
