Does Length, Diameter, or Bone Quality Affect Primary and Secondary Stability in Self-Tapping Dental Implants?

Abstract

IT and primary ISQ in self-tapping implants differed in patients with different bone quality and implant diameter but did not differ between the 2 implant lengths compared in this study. Secondary stability was not substantially affected by any of these factors. Although IT was closely related to primary ISQ, it was unrelated to secondary ISQ. Very high primary ISQ values tended to decrease, whereas intermediate and low values tended to increase, in the transition to secondary stability.

Insertion Torque of Variable‐Thread Tapered Implants in the Posterior Maxilla: A Clinical Study

“…Similar findings were reported in a human cadaver maxilla model evaluating the primary stability of variable‐thread tapered implants of different diameters . The lack of statistically significant differences in ITVs between different implant lengths is in line with the clinical findings of Gómez‐Polo et al . This can be justified by the fact that implant design may prevail over implant dimensions as a contributing factor in primary stability in some implant systems.…”

“…Similarly, there is a lack of consensus relative to the impact of implant length on ITVs. Implant length seems to be critical in obtaining higher primary stabiltiy in some studies, while others reported no influence of implant length on ITVs . The impact of implant diameter and length on primary stability was not evident in this study, as ITVs did not significantly differ between various implant diameters and lengths in all three bone qualities taken jointly or in D4 bone considered separately.…”

“…Implant primary stability is a key factor in achieving osseointegration and is one of the prerequisites for successful immediate/early loading procedures . Primary stability is affected by multiple factors such as bone quality, bone density, bone morphology, implant design, implant surface roughness, preparation of the implant site, crestal bone anchorage, apical anchorage through the cortical floor of the sinus or nasal cavities, lateral cortical anchorage, and implant dimensions …”

Comparison of clinical and radiographic parameters around short (6 to 8 mm in length) and long (11 mm in length) dental implants placed in patients with and without type 2 diabetes mellitus: 3‐year follow‐up results

“…Experimental results by Soskolne et al (Soskolne et al 2002) showed an increased adherence of monocytes to titanium disks with moderately rough surfaces as compared to plastic surfaces. A recent longitudinal clinical study demonstrated that implant length was not associated with the primary and secondary stability of self-tapping dental implants (Gomez-Polo et al 2016). Although bone quality and PS at the time of implant insertion remained uninvestigated in the present study, it is hypothesized that both groups exhibited a considerable amount of PS and favorable bone type.…”
