Comparing short and standard length dental implants for removable dentures
Clinical Outcome of Subcrestal Short Implant Versus Crestal Standard Length Implant to Retain Kennedy Class 1 Removable Partial Denture: A Split-mouth Study
This study is testing whether shorter dental implants work just as well as standard-length implants for supporting removable dentures in people with missing teeth.

What this trial studies
This clinical trial aims to evaluate the survival rates and clinical outcomes of subcrestal short implants versus crestal standard length implants in supporting removable partial dentures (RPD) for patients with partial edentulism. Thirty participants aged 50 and older, with at least two adjacent missing teeth, will receive both types of implants in a split-mouth design. Various parameters, including plaque index, bleeding on probing, probing depth, and radiographic crestal bone levels, will be assessed at multiple time points: implant placement, restoration delivery, and three-year follow-up. Statistical analysis will be conducted to determine the significance of the findings.
Who should consider this trial
Good fit: Ideal candidates are adults aged 50 years or older with class 1 removable partial dentures and missing mandibular molars who experience instability of their prosthesis.
Not a fit: Patients with active infections, systemic diseases like diabetes, or those who have undergone recent radiation therapy to the head may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide insights into the effectiveness of short implants, potentially improving treatment options for patients with limited bone height.
How similar studies have performed: Previous studies have shown promising results with similar approaches, indicating potential for success in this trial.
Eligibility criteria

Inclusion Criteria * adult patients aged 50 years or older with class 1 RPD with missing mandibular molars at least and complaining from instability of the prosthesis were recruited. * Medical history revealed no contraindication to implant therapy. * Patients have an amount of bone nearly equal to 8 mm length above the inferior alveolar canal to receive a 6 mm short implant with 2 mm subcrestal to the bone level with sufficient bone width ≥ 8mm on one side and an amount of bone equal to or more than 8 mm to receive a standard-length implant of 7.5, 9, or 10.5 mm placed at crestal bone level with sufficient bone width ≥ 8mm on the contralateral side which was examined by CBCT. Exclusion Criteria: * Presence of active infection or inflammation in the areas intended for implant placement; \*systemic diseases such as diabetes. * Pregnant and lactating patients. * Habit of severe bruxism or clenching. * Treatment with therapeutic radiation to the head within the past 12 months. * Treatment with bisphosphonate within the past 12 months. * More than 10 cigarettes/day smoking habit.
