Summary

Background: In cases with atrophic posterior maxilla, sinus elevation techniques are essential for a successful implant placement. The optimal strategy for treating pneumatized maxillary sinus in terms of dental implant insertion and surrounding bone stability has been a scientific conundrum for many years. The objective of this study was to evaluate and contrast the long-term marginal bone alterations around dental implants that were positioned utilizing transcrestal (closed) versus lateral (open) sinus elevation procedures. Material and methods: Fifty six dental implants were inserted for patients with inadequate residual bone height due to maxillary sinus pneumatization after receiving approval from Suez Canal University's ethics council. Depending on the method, these patients were randomly assigned to one of two groups: the test group, which received the closed sinus elevation, or the control group, which received the open sinus elevation.Allogenic bone grafting was used to treat the elevated sinuses in both groups.The mesial and distal marginal bone loss for these dental implants was evaluated over a 12-month period following surgery using a standardized digital periapical radiography and the Cliniview Software to measure radiographic bone alterations.
