Digital planning in GBR: customized bone regeneration^® in complex bone augmentation
Prof. Dr. Bilal Al-Nawas

Vertical bone augmentation requires space maintaining elements to provide graft stability but are associated with time consuming procedures. 3D printing technology offers new opportunities to reduce surgical time due to customization and supports planning of bone regeneration and implant positioning in a digital workflow.

The Osteology Foundation promotes research, education and collaboration between universities and industry in the field of oral and maxillofacial tissue regeneration. The objective is to make new techniques and products available to practitioners quicker and with greater goal orientation. True to its motto “2020 Vision for Regeneration”, the Osteology Foundation aims to bridge the gap between scientific progress and clinical practice, as well as...

Prof Urban's sold out workshop.

Theoretical background:

• Is guided bone regeneration a safe therapy and what is known about long-term results?

• New innovative clinical approaches will be demonstrated to solve the problem of hard- and soft tissue volume stability

• Are there reliable off-the-shelf solutions that will bring us to the next level of soft tissue regeneration

Hands-on parts – techniques presented:

• New surgical techniques for simultaneous GBR and Implant placement using stabilized graft materials (L-shape technique)

• Handling of the GBR materials

• Stabilizing graft materials

• Handling and management of the soft tissues

Model: pig jaw

Different reconstructive procedures are nowadays available to allow for implant placement in severely atrophic partially or totally edentulous ridges, such as GBR with particulate grafts with resorbable or non-resorbable membranes or autogenous bone block grafts. These procedures are both reliable, but sometimes time-consuming and very technically demanding in terms of adaptation and fixation of the grafts, both particulate or in blocks.

Recently, customized, CAD/CAM titanium meshes are available on the market with the aim of offering results similar to those obtained with the traditional reconstructive procedures, whilst also allowing for the relevant simplification of the surgical procedure.

The production of these Ti-Meshes is in fact performed on personalized 3-D models obtained by CBCTs of the atrophic area of each patient, allowing an extreme precision and simplification of the adaptation of the mesh to the defect to be reconstructed.

The aim of this workshop is to teach all participants how to perform all of the surgical steps of the reconstructive procedure of partially edentulous jaws with customized Ti-Meshes with the aid of both didactic (including detailed slides & procedural videos) and hands-on (using both animal (pig jaw) and synthetic models) sessions.

LEARNING OBJECTIVES

1. How to optimize pre-operative planning of a clinical case in need of reconstruction of an atrophic edentulous ridge with a customized Ti-Mesh;

2. How to optimize incision lines of soft tissues to access the defect;

3. How to choose the grafting materials for guided bone regeneration (GBR) with Ti- meshes;

4. How to harvest bone chips with bone scrapers from intra-oral sites (mandibular ramus; hands-on exercises using an animal (pig jaw) model );

5. How to optimize the combination of autogenous bone chips with bovine bone mineral for GBR (hands-on exercises using a synthetic model simulating an edentulous area of the jaw);

6. How to adapt the preformed Ti-Mesh to the defect and how to stabilize it with titanium screws (hands-on exercises using a synthetic model simulating an edentulous area of the jaw);

7. How to optimize the use of collagen membranes over the Ti- Meshes prior to soft-tissue closure;

8. How to release mucoperiosteal flaps to obtain a water-tight and tension-free suture (hands-on exercises using an animal (pig jaw) model).
