Abstract
Objectives
Initial implant stability is one of the fundamental criteria for obtaining osseointegration. The aim of this study was to establish a correlation between the primary stability of short and normal implants placed in different types of bone density.
Methods
A total of 60 Nobel Biocare implants (Göteborg, Sweden®) of different length and design were inserted in 7 maxillae and mandibles of recently deceased persons (20 Replace Select® Straight 10 ´ 4.3 mm, 20 Replace Select® Tapered RP 10 ´ 4.3 mm and 20 Nobelspeedy Shorty® RP 7 ´ 4 mm). Histomorphometry was carried out to analyze the different local bone volume and the bone-to-implant contact (BIC).
Results
The mean BIC for the three implant types varied strongly in the maxilla (Replace Select® Straight 0.78% ± 1.0; Replace Select® Tapered 1.3% ± 1.2; Nobelspeedy Shorty® RP 2.35% ± 1.7) but was very similar in the mandible. A comparable pattern was found for the amount of bone tissue present within distances of 0.2 mm and 1.0 mm around the implant. All measured parameters were numerically higher in the mandible than in the maxilla.
Conclusions
The fact that shorter implants showed numerically higher values of BIC and BV/TV in the upper jaw, suggests that they may improve implant therapy in cases of poor bone supply in this region. The lack of such differences makes the existence of a similar effect less likely in the lower jaw.
