Context:This article presents an original research conducted at Government Dental College, PGIDS, Rohtak.Aims:(1) To evaluate the marginal bone level changes around dental implants based on the radiological examination. (2) To evaluate the relationship of various parameters, i.e., gender, implant length, implant diameter and location of implants on the amount of bone loss around dental implants.Materials and Methods:An in-vivo study was undertaken to evaluate the crestal bone loss on mesial and distal aspect of implants, using standardized intra-oral periapical at the end of 6 months after placing the implants, but before prosthetically loading it.Statistical Analysis Used:Student's unpaired t-test.Results:Bone loss was measured and values were recorded immediately after implant placement and after 6 months.Conclusions:(1) Bone loss on mesial and distal aspects of implants was found to be same after period of 6 months. (2) Bone loss was found to be same in both 13 mm and 10 mm implants on mesial aspect, whereas on distal aspect, it was more in 10 mm implants. (3) Bone loss was found to be same in both 3.5 mm and 4.3 mm diameter implants on both mesial and distal aspects of implants. (4) Bone loss was found to be same in both maxilla and mandible on both mesial and distal aspects of implants. (5) Bone loss was found to be more in females on both mesial as well as distal aspects of implants.

In past, the materials used for denture bases were vulcanite, celluloid & phenol formaldehyde. Acrylic resins were introduced to dentistry in 1930's. There are certain limitations of acrylics like residual monomer allergy, poor mechanical strength, low fatigue strength, brittle on impact, poor conductors of heat, low hardness, high coefficient of thermal expansion, thermal shrinkage, poor color stability of self-cured resins, porosity, crazing, warpage, poor adhesion to metal and porcelain and requirement of mechanical retention. But still they are the most widely used denture base materials till date. But recently there has been much advancement in the field of denture base resins to overcome their drawbacks and to obtain an ideal denture base material. This article reviews the various advancements in the field of denture base resins.

Introduction: Vitamin D has been shown to play a vital role in bone mineral homeostasis by stimulating the intestinal absorption of calcium and phosphate. The critical role of Vitamin D in bone metabolism triggered the need to evaluate the effect of Vitamin D deficiency and hence replacement of the same on osseointegration of dental implants. This prospective study evaluated the crestal bone level in patients having low level of Vitamin D treated with dental implant with or without Vitamin D3 supplements. Materials and Methods: A prospective clinical study was conducted on 32 patients based on the inclusion and exclusion criteria. Patients were divided into two groups on the basis of Vitamin D level < 30 ng/ml (Group I: patients receiving Vitamin D3 supplements, i.e., cholecalciferol 1 g sachet 60,000 IU/month) or <30 ng/ml (Group II: not receiving Vitamin D3 supplements). The crestal bone level measurements were made with the help of Digimizer Image Analysis, MedCalc software. Results: All implants showed clinically acceptable crestal bone level at interval of 1 week (baseline), 3 months, and 6 months. There was a statistically nonsignificant difference seen for the values between the groups ( P > 0.05) for all other values at various time intervals. However, there was a statistically significant/highly significant difference seen for the values between the groups ( P < 0.01, 0.05) for 3 months distal with higher values for Group I as compared to Group II. Conclusion: From the study, it can be concluded that cholecalciferol has systemic effects on accelerating bone formation around titanium implant.

The aim of this article was to study a case report of full mouth rehabilitation in a severally periodontally compromised patient in which 18 single piece basal implants were inserted and functionally loaded with both maxillary and mandibular cement retained fixed partial denture. Basal implants were loaded immediately, and excellent results were obtained. Bone loss was measured and values were recorded immediately after implant placement and after 6 months. Basal implants are used to support single and multiple unit restorations in the upper and lower jaws. They can be placed in the extraction sockets and also in the healed bone. Their structural characteristics allow placement in the bone that is deficient in height and width. Basal implants are the devices of the first choice, whenever (unpredictable) augmentations are part of an alternative treatment plan. The technique of basal implantology solves all problems connected with conventional (crestal) implantology.
