Objectives:
This clinical comparison study compared between different designs of solitary attachments used to retain implant
assisted mandibular distal extension RPD regarding alveolar bone height changes around abutment teeth.
Methods:
Twelve patients with mandibular Kennedy Class I were selected for this study. The remaining natural teeth were
extended from the first premolar on one side to first premolar on the other side. One implant was placed in each first molar
region bilaterally. The removable partial dentures were retained anteriorly by RPA clasp design and posteriorly either by ball
attachment (group I) or by OT-equator attachment (group II). Alveolar bone height changes around the primary tooth abutments
were radiographically evaluated using cone beam volumetric CT.
Results:
Regarding bone loss around the primary abutment teeth, Ball attachment group (0.72 ± 0.15) significantly (p value =
0.008) showed less crestal bone resorption when compared to OT-equator attachment group (1.01 ± 0.25).
Conclusion:
Within the limitation of this study and regarding the preservation of abutment teeth, the use of ball attachment may
be the suitable choice for anchoring distally extended removable partial denture to dental implants with improved longevity of the
natural tooth abutments.
