Immediate Placement and Loading of Hybrid-Design Implants in the Posterior Region Using Optimized Digital Protocols:
Purpose:
To use a hybrid/tissue-level implant design for immediate placement and immediate loading in the posterior region applying a digital workflow.
Materials And Methods:
In total, 12 patients with a single tooth to be extracted in the posterior maxilla or mandible were consecutively recruited. A CBCT examination and an intraoral scan were performed, and the digital data were used to fabricate a surgical guide and a provisional restoration for immediate loading. A flapless extraction was performed, and an implant with a hybrid design was placed in the extraction socket using a fully guided protocol. A prefabricated screwretained provisional prosthesis was then placed in full occlusion. After 2 to 3 months, a final intraoral scan was performed, and a definitive prosthesis was delivered. Patient-reported outcome measures (PROMs), marginal bone loss (MBL), and probing depth (PD) were recorded over a period of 6 months. Statistical analyses were performed using paired t test.
Results:
Stable clinical (mean PD 2.8 ± 0.5 mm) and biologic (mean PI 4.9% ± 5%) outcomes were observed for all implants, rendering a 100% success and survival rate. PROMs were 9.5 ± 0.5 at baseline and 9.7 ± 0.4 at 6 months of follow-up.
Conclusions:
The use of hybriddesign implants placed immediately and subjected to immediate loading presents a viable treatment option in the posterior maxilla and mandible. Randomized controlled clinical trials should be performed with a larger sample size to further recommend such an approach for daily clinical use.
