Summary
The Simplant software modeled mandibular ridge reconstruction techniques. The boxing technique most closely replicated ideal bone geometry, regardless of the initial ridge shape, offering superior pre-implant reconstruction.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Biomaterials Science
Background:
- Pre-implant reconstruction of edentulous mandibular ridges traditionally focuses on height and width, neglecting initial geometry.
- Simplant® software enables advanced modeling of these techniques, incorporating initial ridge geometry for enhanced planning.
Purpose of the Study:
- To evaluate and compare four crestal volume reconstruction techniques for the edentulous mandible.
- To assess the effectiveness of Simplant® software in modeling these techniques based on initial crestal geometry.
Main Methods:
- Four surgical techniques (apposition, interposition, distraction, formwork/boxing) were applied to seven hemi-mandibles.
- Simplant® software was used to model the reconstructed bone volume in relation to the initial crestal geometry.
Main Results:
- Average height gains: Onlay graft (4.1mm), Interposition graft (2.3mm), Distraction (4mm), Boxing (5.1mm).
- Average crestal width gains: Onlay graft (-0.3mm), Interposition (1mm), Distraction (-0.5mm), Boxing (1.3mm).
Conclusions:
- Simplant® software modeling indicated that the boxing technique provides the most accurate bone reconstruction aligning with ideal crestal geometry.
- The boxing technique's efficacy in achieving ideal bone geometry is independent of the initial crestal geometry.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:31Bone Remodeling and Repair
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
