Surgical procedures for the application of implants in the lateral-superior sectors are affected by the availability of the residual bone. When this condition is lower than 5 mm it is recommended that techniques involving two therapeutic phases, a reconstructive and an applicative one, as reported in the international literature, are adopted. The authors propose here a new method with the potential to apply implants simultaneously with the reconstructive phase. The aim of this longitudinal retrospective study was to evaluate the stability of implants applied with the fit lock technique in the upper maxillarys in us with bone availability lower than 4 mm by measuring resonance frequency at different follow-up periods The seme as urements, carried out on 30 implants, were analysed with specific statistical procedures. The results indicate that the stability of the implants inserted with the fit lock method increases progressively over time in a statistically significant manner. The stability recorded after one year from the insertion (ISQ T2) is significantly higher than that recorded after six months (ISQ T1), and this is significantly higher than that recorded at the time of implant placement (ISQ T0). The implants inserted in the maxillary zones with scarce bone availability and applied with this technique showed a similar stability as reported with other techniques. In light of the results, the authors confirm that the primary stability represents the basic requirement to guarantee a correct healing of the implant and demonstrate that the fit lock technique also all ows reaching this condition when bone availability is minimal.
在上颌外侧上部区域应用种植体的外科手术会受到剩余骨量的影响。当剩余骨量低于5毫米时，建议采用国际文献中报道的包括重建阶段和植入阶段的两阶段治疗技术。本文作者提出了一种新方法，有可能在重建阶段同时植入种植体。这项纵向回顾性研究的目的是通过在不同随访期测量共振频率，评估在骨量低于4毫米的上颌骨中采用适配锁定技术植入的种植体的稳定性。对30颗种植体进行的测量结果采用特定的统计程序进行分析。结果表明，采用适配锁定方法植入的种植体的稳定性随时间推移以统计学显著方式逐渐增加。植入后一年（ISQ T2）记录的稳定性显著高于六个月时（ISQ T1）的记录，且六个月时的稳定性显著高于种植体植入时（ISQ T0）的记录。在骨量稀少的上颌区域采用该技术植入的种植体显示出与其他技术报道的类似稳定性。根据结果，作者确认初始稳定性是保证种植体正确愈合的基本要求，并证明当骨量极少时，适配锁定技术也能达到这一条件。
