Detaljert beskrivelse
Objective: - To evaluate histologically the influence of the functional load on implants, both immediate and delayed.
Material and methods: 12 participants with edentulous alveolar crests in the distal portion of the arches will be included in the study. At least two implant sites will be identified in each patient and will be sub-prepared with drills or sonic instruments to obtain a high degree of torque to ensure optimum primary stability. At least one site will be used as a test and one as a control where experimental mini-implants will be installed. Test sites will be loaded immediately. The control sites will remain unloaded. After 2 months, mini-implants will be recovered as planned for each group. Reconstructive surgical procedures will be applied at the biopsy sites, if necessary, using autologous bone or bone substitutes and membranes. Standard implants will be installed during the same surgical session and, after 2 months, the planned prosthesis will be performed. Patients will be followed for at least 2 years for evaluation and intervention, if necessary.
Biopsies will be included in resin to obtain wear cuts for histomorphometric analysis. The bone histomorphometry will be evaluated and statistical analysis will be carried out.

Eksperimentell: Immediate implant Loading
Immediate loading is defined as the placement of the implant and immediate prosthetic restoration
|
The participants will be assigned to immediate or delayed functional loading groups. In each participant, edentulous areas with adequate thickness of the alveolar bone crest will be identified and at least two sites will be identified for implant installation. All implant recipient sites will be sub-prepared to allow good stability of the implants. Experimental mini-implants (Sweden & Martina, Due Carrare, Padova, Italy), 3.5 mm in diameter and with an intraosseous portion of 4 mm in length will be installed. Immediate loading group - A prosthetic component will be applied over the trial implants. Impressions will be taken and a crown / bridge will be provided to patients in one day.
