Indications for Simultaneous Implantation and Bone Augmentation Using the Allograft Bone Ring Technique.

Area of Science:

• Oral and Maxillofacial Surgery
• Periodontology
• Dental Implantology

Background:

• Dental implant therapy frequently necessitates bone augmentation for stable placement and predictable results.
• Guided bone regeneration (GBR) traditionally uses barrier membranes to direct tissue growth in sites with insufficient bone volume.
• GBR and implant placement can be performed in one or two surgical stages.

Purpose of the Study:

• To present a novel simultaneous approach for dental bone augmentation and implant placement.
• To describe the use of a custom-milled cancellous allograft bone ring stabilized by the dental implant.
• To outline indications for this technique, including sinus deficiencies and various bone wall defects.

Main Methods:

• Utilizing a custom-milled cancellous allograft bone ring for bone augmentation.
• Stabilizing the allograft bone ring through graft preparation and the apical threads of the dental implant.
• Performing simultaneous implant placement with bone augmentation in a single surgical procedure.

Main Results:

• The described method facilitates simultaneous implant placement and bone augmentation.
• The custom bone ring provides stability and promotes regeneration in deficient sites.
• The technique is applicable to sinus augmentation and defects with one to four bone walls.

Conclusions:

• A novel simultaneous approach using a custom allograft bone ring offers a predictable method for bone augmentation and dental implant placement.
• This technique simplifies treatment by combining bone regeneration and implant surgery into one stage.
• The method is suitable for a range of bone deficiencies, enhancing treatment options for complex implant cases.
