In the article, the authors reveal the significance of traumatic occlusion in patients using fixed bridges fixed on dental implants. In the study, the authors use the method of occlusionography to reveal traumatic occlusion in the area of bridges fixed on dental implants. Selective grinding is carried out in the position of central occlusion from the occlusal surface of bridges and antagonist teeth. Radiographically, the authors assessed the degree of bone resorption in the area of implants at various times of the study. The examined patients were divided into 3 groups, of which group I consisted of 8 patients using bridges with implant support, group II - 10 patients with single artificial crowns on implants, group III - 13 patients using metal-ceramic bridges with based on devitalized teeth and implants. The appropriate distribution of patient groups was aimed to obtain comparative results of selective grinding in different clinical cases. The results of the study revealed a significant improvement in the processes of osseointegration in the area of implants using the method of selective grinding. Radiographically confirmed the normalization of the processes of osseointegration and the formation of mature bone tissue in the elimination of traumatic occlusion in the area of bridges fixed on dental implants.

Changes in alveolar ridge in terms of volume, height and morphological features tend to be clinically significant and may result in difficulty for the placement of a conventional bridge or an implant-supported crown. Bone deformities or resorption from tooth removal can be prevented by a procedure called socket preservation. Studies have discussed the rationale of performing socket preservation as a therapeutic procedure following tooth extraction which includes the procedure done during or after the removal of tooth in order to reduce the risk of external ridge resorption and increase the formation of bone with the socket. This study aims to evaluate the site predilection for socket preservation in maxillary and mandibular anterior teeth following extraction. It is a retrospective study conducted by reviewing 86,000 patient case records of the Saveetha Dental College and Hospital, Chennai, India. A total of 25 consecutive case records of patients for a period of October 2019 to March 2020 with signed informed consent were selected from the Departments of Prosthodontics and Implantology based on the inclusion criteria of patients who have undergone socket preservation procedure indicated for implant placement. Information such as patient’s name, patient’s identification number (PID), age, gender and area of socket preservation were retrieved from the patients’ case records. Datas were entered in Excel and analyzed using SPSS software version 23.0. Descriptive analysis was done for the assessment of age, gender and area of socket preservation. Chi-square test was used to evaluate the association of socket preservation with age and gender. Significant level test was set at less than or equal to 0.05 (p≤0.05). In this study, higher prevalence of socket preservation was seen in the upper anterior region (60%) than the other sites. Most cases of socket preservation were seen in males (80%) as compared to females (20%). Socket preservation was done mainly in individuals within the 21-30 years age group.Within the limits of the study, socket preservation is done mainly in individuals within the 21-30 years age group with higher predilection in males compared to females. Most of the socket preservation procedures are done in the upper anterior region, followed by upper posterior, both upper anterior and posterior and lower posterior. However, there is no significant association between the area of socket preservation with age and gender.

The human body is constantly changing. Scientific evidence shows that alveolar bone undergoes changes after extraction. These changes continue as time of edentulousness progresses. These changes continue occurring even after prosthesis is inserted.Different methods for the assessment of alveolar bone height have been commonly used in practice out of which the panoramic radiograph is excellent for visualization of general structures of the face. The aim of this study is to compare the bone levels in dentate and edentate areas of the mandible with orthopantogram. A retrospective study done in the Department of Prosthodontics, Saveetha Dental College. Data was collected from a total of 86000 patients who visited Saveetha dental college between Jun,2019 to March,2020. Out of this, OPG of 40 patients in the age group of 35-50 years and who fell in Kennedy's Class 1 classification of mandible were retrieved for the study. The OPG was analysed in ImageJ software. The bone height was measured from the inferior border of the mandible and the crest of the ridge in edentulous areas; the inferior border of the mandible and the alveolar crest in the dentulous areas. The height was obtained in pixels from the software which was later converted into distance in millimeter (mm). The data obtained was tabulated in SPSS for windows, version 20. Paired t-test was done to determine difference in the bone levels of dentate and edentate regions.The paired samples t-test revealed statistically significant difference between dentate and edentate regions in both males (P=0.000) and females (P=0.000). The correlation between dentate and edentate regions for males and females was also statistically significant with P=0.011 and P=0.000 respectively. Pearson correlation was done between gender and difference in bone levels in dentate and edentate regions was not statistically significant with P=0.342. However, Pearson correlation was done between age and difference in bone levels in dentate and edentate regions was statistically significant with P=0.031. The present study was conducted to understand the correlation between bone levels in the dentate and edentate areas of patients with Kennedy's class 1 mandible. Within the limitations of this study, it can be concluded that there is significant difference in the bone levels of dentate and edentate areas in both male and female patients.
