Brief Summary
The investigators aim to determine the level of total bone volume remodeling at 6, 24 and 36 months post-surgery in patients who underwent immediate prosthetic rehabilitation through a cranial bone-grafted maxilla in combination with immediate provisional implant (IPI) placement.

Outcome Measures
Primary Outcomes (1)
mean total bone volume changes (%)
6, 24, and 36 months post surgery
Secondary Outcomes (8)
correlation between biologic risk factors, as collected through medical files and patient interview, with undesirable bone volume changes
short-term (6 months)
correlation between biologic risk factors, as collected through medical files and patient interview, with undesirable bone volume changes
long-term (24 months)
correlation between biologic risk factors, as collected through medical files and patient interview, with undesirable bone volume changes
long-term (36 months)
correlation between mechanical risk factors, as measured through clinical or radiographical visualization by the treating surgeon and/or prosthodontist, with undesirable bone volume changes
short-term (6 months)
correlation between mechanical risk factors, as measured through clinical or radiographical visualization by the treating surgeon and/or prosthodontist, with undesirable bone volume changes
long-term (24 months)
- +3 more secondary outcomes
Study Arms (1)
CBCT arm
all participating patients receive an additional CBCT scan at 24 and 36 months, for analysis of evolution of bone volume
Interventions
additional CBCT scan at 24 and 36 months, for analysis of evolution of bone volume
Eligibility Criteria
You may qualify if:
- Patients of all ages
- Patients with moderate to extreme bone atrophy of the jaw (class IV to VI according to Cawood and Howell (Cawood \& Howell, 1988), caused by terminal periodontitis or edentulism
- Patients requiring bone augmentation procedures through cranial bone-grafting for jaw reconstruction
- Patients requesting immediate prosthetic rehabilitation, through the placement of an immediate provisional implant (IPI)-supported fixed bridge (immediate loading)
You may not qualify if:
- Patients not fulfilling abovementioned criteria
- Patients with severe uncontrollable diabetes
- Patients with a smoking habit of \>10 cigarettes/day
- Patients with severe sinusitis problems
- Patients with insufficient cranial bone thickness
- Patients with bone remodeling or systemic diseases, or undergoing systematically administered treatments affecting bone remodeling
- Patients in whom postoperative complications (e.g. sinusitis, infections) occurred, will be excluded from the analysis, since these could be responsible for short-term bone volume loss confounding long-term results
