Summary
Motorized ridge expanders showed superior bone expansion and primary implant stability compared to osseodensification. This technique is more effective for alveolar ridge augmentation in the anterior maxilla.
Area of Science:
- Dental Implantology
- Oral Surgery
- Bone Augmentation Techniques
Background:
- Adequate bone volume is crucial for dental implant success, influencing primary stability, osseointegration, and long-term survival.
- Non-subtractive bone augmentation methods like ridge expansion and osseodensification are used to achieve sufficient bone volume.
- Motorized bone expanders are commonly employed for anterior maxillary ridge expansion, while osseodensification aims to enhance primary stability.
Purpose of the Study:
- To compare the efficacy of motorized bone expanders versus osseodensification for alveolar ridge expansion in the anterior maxilla.
- To evaluate and compare the primary and secondary implant stability achieved by both techniques.
- To assess bone expansion and implant stability using cone beam computed tomography (CBCT) and implant stability quotient (ISQ).
Main Methods:
- A comparative study involving 30 implants placed in 15 patients in the anterior maxillary region.
- Fifteen implants were placed using the motorized bone expander method (Dentium Ridge Spreader) and 15 using osseodensification (Densah® Bur).
- Alveolar ridge expansion was measured via CBCT, and implant stability was assessed using Osstell (ISQ) at multiple time points.
Main Results:
- Both methods demonstrated significant bone thickness increase (p<0.001).
- Motorized ridge expanders resulted in greater bone thickness increase compared to osseodensification, though not statistically significant between groups post-operatively (p=0.894).
- Implant stability quotient (ISQ) values were significantly higher for osseodensification at one month (p=0.015) but comparable at six months (p=0.592).
Conclusions:
- Motorized ridge expanders were more effective in achieving greater alveolar ridge expansion.
- Motorized ridge expanders also demonstrated superior primary implant stability compared to osseodensification.
- The findings suggest motorized ridge expansion as a more effective technique for anterior maxillary bone augmentation and immediate implant stability.
