Association of Posterior Maxillary Bone Height and Dental Implant Placement: An Institutional Study

This study evaluates the success of dental implants placed in the maxillary posterior region and whether an association exists regarding length and implant success. Dental implants are a surgical component that interfaces with jaw bone to support dental prostheses. In 1978, Brandmarks presented a two-stage threaded titanium root-form implant that has become the best-maintained dental implant. Differences in anatomy make treatment for posterior quadrants more challenging than that for anterior quadrants. The need for dental implants includes partial/complete edentulousness, tooth loss during a mixed dentition period, and immediate replacement due to trauma. This retrospective study was conducted as an institutional setting, and all patients undergoing implant surgery in the maxillary posterior region were considered. We performed Excel tabulation and data analysis using Statistical Package for the Social Sciences (IBM, Armonk, NY). Results show that posterior maxilla bone height was greater in females than males. Patients aged 41-50 yr with bone height of 12-14 mm occurred most often. For implant placement, females showed significant bone height in the posterior maxillary region, and age did not play a significant part in posterior bone height.
