A randomized clinical study to compare implant stability and bone loss using early loading protocol in two implant...

Area of Science:

• Dental Implantology
• Biomaterials Science
• Oral Surgery

Background:

• Early loading protocols in dental implantology aim to accelerate treatment timelines.
• Implant design is a critical factor influencing osseointegration and long-term success.
• Understanding the biomechanical properties of different implant designs is essential for predictable clinical outcomes.

Purpose of the Study:

• To compare the effects of two distinct dental implant designs on implant stability and marginal bone loss.
• To evaluate the clinical performance of implants with flared crest modules and buttress threads versus parallel crest modules and V-shaped threads under early loading conditions.

Main Methods:

• An in vivo comparative study involving 40 subjects with missing single posterior mandibular teeth.
• Randomized allocation into two groups (Group X and Group A) for early loading at 6 weeks.
• Assessment of implant stability using Ostell measurements and evaluation of crestal bone loss via intraoral periapical radiographs analyzed with ImageJ software at multiple time points.

Main Results:

• Group X implants exhibited significantly less mean bone loss (1.51 ± 0.20 mm at 6 weeks, 2.11 ± 0.21 mm at 3 months, 2.13 ± 0.21 mm at 6 months) compared to Group A (1.79 ± 0.16 mm at 6 weeks, 2.92 ± 0.23 mm at 3 months, 2.95 ± 0.23 mm at 6 months).
• Statistical analysis revealed significant differences in bone loss between the groups at all measured intervals (P < 0.05).
• Group A showed highly significant bone loss at 6 months (P < 0.001).

Conclusions:

• The dental implant design of Group X, characterized by flared crest modules and buttress threads, offers superior implant stability and promotes reduced marginal bone loss.
• This specific implant design may be more advantageous for early loading protocols in the mandible.
• Further research could explore long-term outcomes and biomechanical analyses of these implant designs.
