Summary
The purpose of this study is to evaluate the survival rate of 5 mm short implants compared to longer implants (10 mm) placed in sinus-grafted sites.
Primary aim: Compare bone loss between the two groups Secondary aim: Compare surgical time and patient-reported outcomes (satisfaction and post-operative pain)
Eligibility Criteria
Inclusion Criteria
- Age 20-70 years at enrollment
- 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
- Unlikely to be able to comply with study procedures
- 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)
