Summary
Immediate progressive loading of dental implants shows better bone density and height compared to immediate functional loading. This suggests gradual stimulation promotes denser bone growth over two years.
Area of Science:
- Dental Implantology
- Biomaterials Science
- Oral and Maxillofacial Surgery
Background:
- Evaluating changes in peri-implant bone structures.
- Comparing two immediate loading protocols for mandibular implants.
Purpose of the Study:
- Assess bone changes with immediate functional loading versus immediate progressive loading.
- Determine the impact of loading protocols on implant supporting structures.
Main Methods:
- 30 implants placed in 5 patients (Kennedy Class I mandibular).
- Bilateral placement in posterior mandible, comparing protocols side-by-side.
- Dental computed tomography used for radiographic evaluation over 24 months.
Main Results:
- Immediate progressive loading showed significantly better crestal bone height (P=0.011).
- Higher crestal peri-implant bone density observed in the progressive loading group (P=0.009).
Conclusions:
- Immediate progressive loading offers a more predictable bone response and better implant prognosis.
- Gradual loading may enhance bone maturation and density over a 2-year period.
