Abstract
The present study aimed to compare the stability of dental implants placed in low-quality bone prepared for the healing chamber with osseodensification technique and a standard undersized drilling. Sixteen subjects presenting D3 or D4 bone density according to Misch’s classification were randomly distributed to receive dental implants following either osseodensification (G1: n = 29) or standard undersized drilling (G2: n = 26) preparation techniques. Implant insertion torque (IT) and implant stability quotient (ISQ) were measured immediately after implant placement. Implant survival and secondary stability (ISQ) were evaluated after six months. The G1 group showed higher IT (39.0 ± 6.4 Ncm) than G2 (32.0 ± 3.4 Ncm) (p < 0.001). ISQ values were similar (p > 0.05) at the implant insertion (67.1 ± 3.2 and 65.5 ± 2.7 for G1 and G2, respectively). After six months healing, implant survival was equally comparable in both groups (p > 0.05), and ISQ values were higher than those of implant insertion (p < 0.001) but similar (p > 0.05) for both groups (74.0 ± 3.6 and 73.3 ± 3.2 for G1 and G2, respectively). Within the limitations of this study, the present RCT demonstrated that a wider surgical bed prepared by osseodensification instrumentation allowed for the bone healing-chamber concept in low-quality bone without any reduction in implant stability and success rate.
Highlights
The survival of dental implants depends on the bone’s ability to remodel at the bone–implant interface [1,2]
The purpose of this study was to evaluate the primary and secondary stability of dental implants placed in low-quality bone sites prepared for the healing chamber concept with osseodensification compared to a standard undersized drilling protocol
The study adhered to the ethical values of the Declaration of Helsinki and was approved by the local ethics committee (#7021401700005283)
Summary
The survival of dental implants depends on the bone’s ability to remodel at the bone–implant interface [1,2]. Adequate primary stability is necessary to predict the survival of dental implants This has led to the practice of under-preparing the implant bed to be significantly narrower in diameter than the thread diameter of the implant, especially in soft bone. This is associated with the self-tapping screw implant design, which guarantees a close fit of the dental implant and bone [6,7]. The under-preparation of the implant bed produces high primary stability; it increases peri-implant remodeling and subsequent stability loss during the short-term healing [11]
