Intervention |
CAD-CAM fabricated provisional prosthesis |
Duration: 3 months.
CAD-CAM fabricated provisional prostheses facilitates prosthesis delivery in immediate functional loading protocols. The prostheses are manufactured in the laboratory by milling high-density polymers based on a highly cross-linked polymethylmethacrylate (PMMA). The prostheses are known to have higher biocompatibility, superior esthetics and soft tissue response as compared to denture conversion prostheses.
|
Comparator Agent |
Denture Conversion Prosthesis |
Duration: 3 months.
The denture conversion prosthesis is routinely used for immediate loading of complete-arch fixed implant-supported prosthesis due to its simplicity, adaptability to changes in planned implant positions, and reduced treatment cost. Nevertheless, this is a multistep, technique-sensitive process. Therefore, in this study a comparison between CAD-CAM fabricated prostheses and a denture conversion prostheses will be performed. |

Secondary Outcome

Outcome |
TimePoints |
Survival rates:
To evaluate implant survival rates of tilted and axially placed implants at 1 year, 3 years and 5 years
.
VAS Scores, OHIP-14 scores and Operator based preferences. |
1 year, 3 years and 5 years |
Prosthetic Level:
Incidence of chipping of the final prostheses, fracture of abutment/ crown or frame work, fracture of veneering ceramic, occlusal roughness, loss of retention (loosening of crown or abutment screw) and the contour of restoration will be evaluated at 4 weeks after insertion of final prosthesis and at 1 year, 3 years and 5 years after function for final prosthesis using the Modified USPS scores.
|
4 weeks, 1 years, 3 years and 5 years |
Implant Level:
Fracture of screw and implant will be evaluated at 4 weeks after insertion of final prosthesis (BL1) and at 1 year, 3 years and 5 years.
|
4 weeks, 1 years, 3 years and 5 years |
PROMS:
- VAS scores based questionnaires about maintenance of oral hygiene, ability to speak, comfort and aesthetics will be evaluated at insertion of interim prosthesis ( Visit 3; prior to implant insertion,) at baseline and 3 months after use of provisional prostheses. Similarly VAS scores will be evaluated at the time of insertion of final prostheses (BL1) and at 1, 3 and 5 years after function.
- OHIP-14 will be evaluated at insertion of interim prosthesis (Visit 3; prior to implant insertion, at baseline and 3 months after use of provisional prostheses. Similarly VAS scores will be evaluated at the time of insertion of final prostheses and at 1, 3 and 5 years after function.
|
1 year, 3 years and 5 years |
Operator based preferences:
VAS scores based questionnaires for operator based preferences with respect to the ease of surgery and insertion of CAD-CAM fabricated provisional prostheses and denture conversion prostheses will be assessed after the insertion of provisional prostheses.
|
3 months |
Clinical outcomes:
The following clinical outcomes will be evaluated at baseline after a functional period 3 months for provisional prostheses; and after insertion of final prosthesis (BL1) and after a functional period of 1, 3 and 5 years by using a dental probe
- Probing depth (PD)
- Bleeding on probing (BOP)
- Plaque control record (PCR)

Brief Summary
|
Implant supported restorations are now a predictable treatment modality for the rehabilitation of complete and partially edentulous jaws. The concept of tilted implants is well documented in the dental literature and high implant survival and success rates for rehabilitation of edentulous arches have been reported.Even though the concept of tilted implants is documented in the literature, the majority of the studies performed evaluated the success and survival rates of this technique without a proper control group.Therefore, in this study, besides the comparison between the two different reconstruction workflows , the patients will be randomized to receive axially or tilted implants. Overall, the expected outcome of this study might help clinicians in their decision making-process when rehabilitating cases of atrophic maxilla. |
