“…Rebaudi et al reported an impressive reduction in the stability and reverse-torque levels in the first weeks of healing after forced insertion of mini-implants in undersized sites [32]. Some authors have reported how the preparation of the implant site through a bone condensation method achieves only "the illusion" of stability at the implant insertion by compression of fractured bone fragments on the damaged bone walls of the implant site [43][44][45][46][47]. This process really occurs in well-vascularized sites and in the absence of traumatic bone damage that may cause inflammatory responses and an increase in macrophage activity [16].…”

Background: The conventional drill technique is the most commonly used for the implant site preparation of the desired diameter and length. Ultrasonic implant site preparation (UISP) can also be used to perform an implant site preparation of the desired dimensions. Methods: Implant sites were prepared in fresh bone ribs with two different implant site preparation techniques: implant surgical drills and piezoelectric tips. Samples were analyzed with scanning electron microscopy (SEM) for evaluating the peri-implant bone damage. Result: In the surgical drills group, the cortical bone surface showed several cracks and the bone vascular canals were hidden by a dense smear layer. Cancellous bone showed large irregularities and trabecular fractures. The piezoelectric group showed a clean and smooth cortical bone surface with opened bone vascular canals; the cancellous bone presented a regular morphology, and the trabecular spaces, clearly visible, were free of debris. Conclusions: Ultrasonic implant site preparation showed cleaner bone surfaces and lower bone trauma compared with the preparation using implant surgical drills.

“…The PICO question was: (P) Patients having two or more healed bony sites at mandibular Premolar/Molar area indicated for implant placement. (I) Intervention, bone collection using a trephine bur at 400 rpm speed (9), during the osteotomy site preparation (C) compared to the bone harvested at 1000 rpm drilling speed (16); (O) to compare histologically the bone cells viability in both groups. The study was accepted by the Research Ethics Committee of the Faculty of Dentistry, Alexandria University (IRB NO:00010556 -IORG 0008839).…”

“…On the other hand, many studies reported that raising the drilling speed to a certain level will reduce the cutting time, resulting in less bone destruction and more bone viability (15,16).…”

BACKGROUND: Viability of the harvested bone during osteotomy preparation is affected by the generated heat, which in turn is related to drilling speed and time; this bone viability is considered an indicator of the quality of the harvested autograft. STUDY OBJECTIVE:The aim of this study was to assess the effect of two different drilling speeds on bone cell viability of bone harvested during osteotomy preparation. MATERIALS AND METHODS:A split mouth randomized controlled clinical trial was carried out on 8 patients, 16 mandibular premolar /molar edentulous ridge sites, using a trephine bur, 8 osteotomies were drilled using a speed of 1000 rpm (Control Group) and the other 8 using 400 rpm (Test Group), implants were placed, the harvested bone viability was evaluated histologically in both groups. RESULTS:The histological assessment revealed better viability features in samples harvested using 1000 rpm (Control Group). CONCLUSION: Drilling at 1000 rpm seems to yield stronger autologous bone viability than drilling at 400 rpm.

“…Marzook et al in their research aimed to verify the significance of implant drill speed on heat generation and bone viability at the recipient site of femur bone in 20 rabbits with 3 varying drill speeds of 1000 rpm, 1500 rpm and 2000 rpm. It was concluded that drilling at high speed with irrigation produced less heat and bone viability was not much affected in contrast with lower speed 50 .…”

Background: 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. Aim: 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. Results: 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. Conclusion: 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.
