Custom Bone Regeneration (CBR): An Alternative Method of Bone Augmentation-A Case Series Study

Area of Science:

• Oral and Maxillofacial Surgery
• Regenerative Dentistry
• Biomaterials in Dentistry

Background:

• Edentulous atrophic ridges present a significant challenge for oral rehabilitation with dental implants.
• Guided Bone Regeneration (GBR) is a common technique for bone augmentation, but its reliability can be influenced by materials and surgical approach.

Purpose of the Study:

• To evaluate the reliability of customized CAD CAM titanium meshes (Yxoss CBR® Reoss) for Guided Bone Regeneration (GBR).
• To assess the efficacy of this GBR technique as an alternative method for bone augmentation in patients with atrophic ridges.

Main Methods:

• A clinical study involving nine patients with ten bone defects due to edentulous atrophic ridges.
• GBR was performed using Yxoss CBR® Reoss titanium meshes combined with autogenous bone grafting and heterologous bovine bone mineral grafting.
• A "poncho technique" soft tissue approach was exclusively used for all cases, followed by mesh removal and implant surgery after a mean 9-month healing period.

Main Results:

• All ten grafted sites achieved a three-dimensional volumetric bone increase, with average horizontal gain of 6.37 mm and vertical gain of 5.95 mm.
• One site experienced titanium mesh exposure, but all sites showed successful bone augmentation without biological complications prior to implant surgery.
• Eighteen implants were placed in the grafted sites with a 100% survival rate.

Conclusions:

• The CBR procedure using Yxoss® by Reoss customized titanium meshes is a reliable and safe method for bone regeneration in horizontal, vertical, and combined bone defects.
• This technique facilitates successful implant-prosthetic restoration in patients with significant bone loss.
• The "poncho" flap approach for soft tissue management is crucial in decreasing the complication of mesh exposure.
