Impact of Drilling Speed in Implantology: A Review

Abstract

<strong>Background:</strong> Drilling speed during osteotomy in implant site preparation is an important factor that affects heat generation, cell vitality and primary stability and consequently Osseointegration of the implant. A thorough understanding of this impact is important for taking suitable precautions for successful dental rehabilitation. <strong>Aim:</strong> The objective of this study is to review the available literature regarding the impact of drilling speed on heat generation and other related parameters that influence the success of dental implants. Material and Methods: Suitable research papers relevant for study were identified through electronic database of available dental literature in PubMed and MEDLINE for all articles published till February, 2021. Peer-reviewed dental and PubMed indexed journals were selected. Search was done using certain relevant key words and terms. <strong>Results:</strong> The initial search revealed a total of 281 articles which were then screened and a total of 61 articles were selected based on the inclusion criteria. Focus was laid on the studies related to drilling speed and its impact on osseointegration, heat generation during osteotomy, drilling speed and bone viability, drilling speed and primary stability of implant and particle size of the bone collected. Heat generation during implant placement is affected by multiple factors with drilling speed being one of them. <strong>Conclusion:</strong> Researchers have reached contradictory conclusions regarding the impact of drilling speed on heat generation during osteotomy and other parameters. However, studies in the recent past are favoring low speed drilling owing to the advantage of perfect control of the drilling depth and the possibility of collection of a considerable amount of viable granular bone grafts during the procedure.
