Comparison of Two Clinical Procedures in Patient Affected with Bone Deficit in Posterior Mandible

摘要

Abstract Background . Edentulous of posterior mandible is common problem of adult patients. It is associated with atrophy of alveolar crest. Sometimes the only way to replace missing teeth are dental implants. Atrophied alveolar crest makes it impossible to use long implants lateralization or short implants are necessary. These procedures have both advantages and disadvantages, however sometimes it is the only way to treat the patients. Objectives . The aim of this study is the comparison of two clinical procedures performed to patients with bone deficit in posterior mandible. Material and Methods . Eighteen patients were divided into two groups depending on the performed procedure (IANL or SIMPL). Patients were between 37 and 58 years old. Before qualification to surgery, patients had CT scans done. In the article two surgical procedures were presented; implants were compared in length, diameter and placement torque, as well as in bone atrophy and complications. Results . It was observed that there is no statistical difference between the treated groups in terms of torque, implant diameter and age of patients. Sensory disturbances after implantations were observed just in the group with IANL (p < 0.001); more implants could be used in IANL (p = 0.04); significantly greater bone loss was observed in implantation with SIMPL (p < 0.001). Conclusion . Patients after IANL, exhibited better implantation results, while patients with SIMPL did not suffer from sensory disturbances.
