Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Systemically healthy patients
* Full-mouth plaque score and full-mouth bleeding score ≤ 30% (measured at four sites per tooth)
* In need of one premolar or 1st molar dental implant in the maxillary area
* Neighboring teeth to the planned implant must have natural root(s) or implant supported restoration.
* Presence of natural tooth/teeth, partial prosthesis and/or implants in the opposite jaw in contact with the planned crown/s deemed by the investigator as likely to present an initially stable implant situation
* Residual bone height under the maxillary sinus between 5 to 7 mm and a width of at least 7 mm, as measured on cone beam computer tomography (CBCT) scans.
Exclusion Criteria
* Uncontrolled pathologic processes in the oral cavity
* History of head and neck chemotherapy within 5 years prior to surgery
* Systemic or local disease or condition that could compromise post-operative healing and/or osseointegration
* Uncontrolled diabetes mellitus HbA1c \>8
* Taking corticosteroids, IV bisphosphonates, or any other medication that could influence post-operative healing and/or osseointegration
* Smokes more than 10 cigarettes/day
* Bruxer
* Present alcohol and/or drug abuser
* Pregnant, unsure pregnancy status, or lactating females (self-reported)
