Immediate versus delayed loading of dental implants
Immediate versus delayed loading of strategic mini dental implants for the stabilization of partial removable dental prostheses: a patient cluster randomized, parallel-group 3-year trial
Mundt et al 2016
- long-term survival data for mini implants are lacking and acceptable short-term survival rates (>90 %) of mini-implants are only documented for mandibular overdentures
- The short-term survival rates of immediate loaded mini-implants that are used to stabilize maxillary overdentures were unacceptably low and ranged between 54 % and 85 %
- The mean radiographic bone loss was >5 mm in the first year and therefore higher than in studies on mandibular overdentures with mean bone loss rates between 0.4 and 1.2 mm
- insertion torque of one MDI was < 35 Ncm.
- the MDIs should be located always mesial of the mental foramen.
- Delayed loaded regulardiameter implants of 15 patients showed bone loss of 0.51 ± 0.39 mm after one year and of 0,62 ± 0.44 mm after 3 years.
- Immediate loaded implants of 15 patients showed bone loss of 0.91 ± 0.63 mm after 1 year and 0.98 ± 0.64 mm after 3 years.
