Implant placement has become a routine modality of dental care.Improvements in surgical reconstructive methods as well as increased prosthetic demands,require a highly accurate diagnosis, planning and placement. Recently,computer-aided design and manufacturing have made it possible to use data from computerised tomography to not only plan implant rehabilitation,but also transfer this information to the surgery.A review on one of this technique called Stereolithography is presented in this article.It permits graphic and complex 3D implant placement and fabrication of stereolithographic surgical templates. Also offers many significant benefits over traditional procedures.
Background: Augmentation of the maxillary sinus increases the lost height of ridge in the posterior maxilla. Bony convolutions from the floor of the sinus called septa may be encountered during the procedure and significantly impact the outcome of the procedure. Materials and Methods: For this retrospective study, 120 cone-beam computed tomography (CBCT) scans were collected from the archives of the department of oral radiology in the time period between January 2016 and August 2018. Planmeca Romexis ® software version 3.2.7 was used to check for the incidence, and then among the septa, plane of orientation, location with respect to the wall of the sinus, and in terms of relation to tooth were examined. The average height and average width of all the septa were measured using a measuring tool in the software. Results: Thirty-five of the total 88 patients showed septa in 40 sinuses, in which 36 sinuses showed one septum and 4 sinuses showed 2 septa. Forty-one septa were located on the floor of the sinus in the frontal orientation and 3 septa were located on the lateral wall of the sinus in the axial orientation. The mean height and mean width of the 41 septa on the floor of the sinus were 5.72 mm and 3.47 mm, respectively. The mean height of septa found on the lateral wall of the sinus was 5.59 mm. Conclusion: Septa had a higher tendency to be in bucco-palatal direction and on the floor of the sinus and frequent occurrence in the region of molars. A thorough prediagnostic evaluation using CBCT is necessary prior to sinus augmentation procedures.
From the study, it was observed that there was no significant variation in the number and extent of wear facets between the cross arch and without cross arch subjects due the smaller sample size hence it was difficult to conclude the relationship non-working side contact as interference and its influence in wearing of dentition in this study.
One of the most challenging and complex treatment modality is replacement of single anterior tooth. This can be overcome by different treatment options such as implant-supported restorations as well as conventional porcelain-fused-to-metal and resin-bonded fixed partial dentures. Drifting of teeth into the edentulous area may reduce the available pontic space; whereas a diastema existing before an extraction may result in excessive mesiodistal dimension to the pontic space. Loop connector fixed partial denture (FPD) may be the simplest and best solution to maintain the diastema and provide optimum restoration of aesthetics. This article describes the procedure for the fabrication of a loop connector FPD to restore an excessively wide anterior edentulous space in a patient with existing spacing between the maxillary anterior teeth.
Background Temporomandibular disorder is the most commonly occurring type of orofacial pain. A general dental practitioner must be able to recognize and distinguish pain related to the joint to be capable of providing treatment or send for a referral. This survey was undertaken to test the undergraduate students in their residency program to analyze their skills in basic understanding and diagnostic capability relevant to temporomandibular joint (TMJ) disorder. Materials and Methods A total of 110 dental students undergoing their residency program in the institute of A.B. Shetty Memorial Institute of Dental Sciences were selected. They were given a questionnaire pro forma to fill out which included questions regarding the anatomy, physiology, pathology, diagnosis, and treatment plan of TMJ disorders. Results Note that 71.75% ± 6.13% of students answered anatomy questions correctly, 46.6% ± 28% answered physiology questions correctly, 34.67% ± 5.5% answered pathology questions correctly, 23.67% ± 2.5% answered diagnosis questions correctly, and 27.25% ± 15.8% answered questions of treatment plan correctly. Note that 100% of them understood the importance of TMJ in dentistry. Conclusion This shows that there is an awareness about the basic understanding of the TMJ; however, to be able to clinically apply the knowledge and diagnose a disorder of TMJ, more than half of the participants were unacquainted of it and the curriculum should stress on improvement of this understanding at the undergraduate level itself.

Preservation of alveolar bone is the main aim of conventional tooth-retained overdenture. In the past when patients reported for a denture with teeth that were badly broken down with periodontal involvement or due to large carious lesions, those teeth were extracted that could have been retained under more favourable conditions. Retention of the roots of one or more teeth for overdenture offers the patient a lot of advantages like better stability, proprioception, support among a few. The following case report focuses on the merits of using selectively retained roots and abutments to minimize alveolar ridge resorption below the complete dentures.
Introduction: Elderly individuals, with or without full dentures, have often been offered probiotics to aid with digestion. An increase in saliva production due to the use of probiotics is noted. Therefore, it was decided to conduct this research to determine the effects of probiotics on the quantity and pH of saliva in patients who are entirely denture-free after 60 days of use. Aim: The goal of this study is to evaluate whether or not probiotic supplementation causes an increase in saliva production in edentulous individuals. Methods: Patients with missing teeth were used in the research. The pH was measured after collecting baseline amounts and baseline amounts of both unstimulated and stimulated saliva. Then, once a day for 60 days, patients took capsules containing probiotics at 3.3 107 CFU/g. Patients' saliva was collected, and its volume and pH were determined for comparison to the initial measurements. Results: After 60 days of taking probiotics, the average amount of saliva, both unstimulated and stimulated, is higher than it was at the beginning of the study. P <0.001 indicates a statistically significant difference. After 60 days, the mean pH was somewhat higher than it had been at the start (0.010). Conclusion: Those with xerostomia or hyposalivation may benefit from taking probiotics, as this study found that they increased saliva production in patients who were completely edentulous.
