Bone Damage during Dental Implant Insertion: A Pilot Study Combining Strain Gauge and Histologic Analysis

Besides alveolar bone quality, the drilling protocol applied in conjunction with design of an implant are major determinants primary stability. Surgical trauma and compression resulting from insertion may constitute one cause for marginal resorption. Inserting two current bone-level designs (Astra; Straumann; n = 5) bovine ribs, stability, strain development on buccal plate histologic signs damage were recorded. comparing (Welch t-tests), all measurement parameters checked potential correlations (Pearson product moment correlation coefficients) level significance set at α 0.05. Considerable numbers crack formation plastic deformation observed after insertion. Straumann implants showed slightly greater values torque (p 0.772), 0.893) stability 0.642). Significantly to contact (cortical p 0.014; trabecular 0.016) was implants, while Astra caused a significantly number microcracks cortical 0.020). In correlated area 0.029) macrocracks 0.029). 0.007) as well 0.016). Additionally, bone, 0.019). Implant placement results varying magnitude, which is governed by drill protocol, macrodesign quality.
