Short Implants and Indirect Sinus Lift Versus Direct Sinus Lift With Standard-Length Implants: A Case Report

Area of Science:

• Dentistry
• Oral Implantology
• Maxillofacial Surgery

Background:

• Dental implant success hinges on implant length, bone quality/quantity, and biting force.
• Advanced alveolar bone resorption, especially in the posterior maxilla, complicates standard implant placement due to anatomical limits and sinus proximity.
• Direct sinus lift procedures can be invasive and increase patient morbidity.

Observation:

• A case study involved a 63-year-old patient with a missing tooth 16 and only 3 mm of residual alveolar bone height.
• Short implants (< 6 mm) were placed after an indirect sinus lift procedure, achieving good primary stability.
• Prosthetic loading occurred after six months, with a one-year follow-up showing no patient complaints.

Findings:

• Indirect sinus lift with short implants is advantageous for posterior maxilla cases with < 4 mm bone height.
• This technique is less time-consuming, surgically less morbid, and more economical than direct sinus lifts.
• The method resulted in superior patient compliance and successful outcomes at one year.

Implications:

• This minimally invasive technique provides a viable alternative for patients with significant maxillary bone loss.
• It enhances patient comfort and potentially reduces treatment costs associated with traditional implant procedures.
• Further studies can validate the long-term efficacy and broader applicability of this combined approach.
