Abstract
INTRODUCTION: Mechanical overload is thought to be one of the major causes of implant complications. The addition of micro threads increase linear length of coronal implant surface available for biologic width and allows some stress transfer and relieve the crestal stress and strain concentration in the coronal region. OBJECTIVES: Was to compare the influence of occlusal loading location on the strain developed around implants with two different crest module designs. MATERIALS AND METHODS: Ten Polyurethane test blocks in which implants were fixed at the maxillary left first premolar area. Specimens were divided into two parallel groups (n=5), Group (I) -implants, with micro threads, Group (II) implants with wide-groove threads. Strain gauges were connected to a strain meter to record the developed strain. A universal testing machine was used for load application up to 100 N. The data were statistically analyzed (p≤0.05). RESULTS: Group I exhibited the lower mean micro-strain values (260.0 ± 192.6 µε) than Group II (513.2 ± 108.2 µε).There was statistically significant difference between both groups(p > 0.05). CONCLUSIONS: Crest module designs affected the stress pattern induced around dental implants
