ClinConnect Summary

This clinical trial is studying two different methods for placing dental implants in patients with a specific type of bone condition in the upper jaw. The researchers want to see how these methods compare in terms of patient experiences, any complications that arise, and the amount of bone loss around the implants after one year. The two approaches being tested are the transcrestal approach with a special technique called osseodensification, and the lateral window technique which involves lifting the sinus. To participate, individuals must be over 18 years old, have lost a tooth in the back of the upper jaw, and have a specific amount of remaining bone height.

Eligible participants can expect to undergo the chosen implant procedure and then complete surveys about their recovery, including aspects like pain, quality of life, and how they feel socially and physically after the surgery. They will have follow-up appointments and imaging to check on their healing and the condition of the implants over the next year. It's important to note that certain medical conditions and habits, like heavy smoking or specific health issues, may exclude individuals from participating in this study.
