简要总结

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)

详细描述

34 patients requiring an implant to replace an upper missing tooth in the premolar or 1st molar area with a bone crest height from 5 to 8 mm will be recruited for this trial. Patients will be randomized to either the test (5-mm implant) or control group (10-mm implant) using a computer-generated randomization list . 17 patients will receive a sinus lift procedure, bone graft, and 10 mm implant while the other 17 patients will receive a 5 mm short implant.

入选标准

  • 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.

排除标准

  • 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
  • Present alcohol and/or drug abuser
  • Pregnant, unsure pregnancy status, or lactating females (self-reported)

结局指标

主要结局

Change in Mesial-distal (M-D) Bone Loss

时间窗: Baseline, surgical visit 1 day, 4 months, 5 months, 12 months, 24 months

Comparing mesial-distal (M-D) bone loss between the two groups. This will be measured in millimeters using standardized radiographs of the implant site at the screening visit, surgical visit, 4 months post-op, 5 months post-op, 12 months post-op, and 24 months post-op visits.

次要结局

  • Survival Rate(5 month post-op, 12 month post-op, and 24 month post-op visits)
  • Number of Sites With Bleeding on Probing(5 month post-op, 12 month post-op, and 24 month post-op visits)
  • Probing Pocket Depth(5 month post-op, 12 month post-op, and 24 month post-op visits)
