Abstract

Background: Edentulism is one of the most commonly encountered condition affecting the oral cavity. Dental implants have emerged as a widely accepted prosthetic treatment option. However, lack of public awareness and cost of the treatment act as barriers which limit their applicability. Materials and Methods: A questionnaire-based survey was conducted in five dental colleges in the state of Himachal Pradesh, India to assess the knowledge, attitude and perception of participants regarding the importance of replacing missing teeth and dental implants. Statistical analysis Used: Epi-info software version 7. Results: Majority of the patients were partially edentulous and believed that replacement of missing teeth is important but only half of participants had undergone treatment for the same. A large number of patients were aware about tooth replacement options but the awareness regarding dental implants was scarce. Conclusion: High cost and lack of information seem to be the major barriers in delivering dental implant treatment. Efforts are needed to educate and spread the awareness about implants among general population. Keywords: Awareness, Dental implants, Edentulism, Knowledge, Perception, Tooth replacement.

Abstract

Introduction: Insertion torque imposes a direct effect on the stability of implants. Some studies suggest that high torque has resulted in bone necrosis while some suggest no impact on bone with high torque, the literature regarding insertion torque relationship to changes in bone is sparse. Purpose: The rationale of this article is to critically evaluate the available scientific data on influence of insertion torque on implant success. Materials and Methods: A Medline and manual search was done to recognize studies that are concerned with insertion torque related implant success rates from 1970 to 2017. The articles taken in this study includes data on insertion torque such as primary stability, bone quality and quantity, implant design and changes in bone related to high or low torque. Results: The 28 included studies contains one randomized controlled trial, 12 prospective studies and 10 retrospective studies. Conclusion: Insertion torque leads to primary stability of implants which ultimately contributes to implant success. Keywords: Insertion torque, Primary stability, Bone density, Implant success.
