Clinical case description:

Guided Bone Regeneration in Alveolus Fresh Severely Reabsorbed.

Description:

Extensive alveolar resorption due to infectious inflammatory lesion in the tooth 34. Held extraction, mucoperiostal to expose the entire area involved, alveolar curettage for removal of all granulation tissue, showing bone resorption of much of the buccal and lingual walls ( figure a1).

Option to use Geistlich Bio-Oss® collagen as filling material because the defect did not have enough bone preserved walls to accommodate and stabilize particulate matter (Figure A2). Furthermore, titanium mesh was used covering the glue to maintain a framework and guided bone regeneration (Fig a3).

About titanium mesh was used in double layer, Geistlich Bio-Gide® membrane collages as a barrier to the migration of soft tissue through the pores of the fabric and thus within the focus area of the bone regeneration (Fig a4).

After 10 months an implant 3.75 mm diameter by 13mm in length with the upper locking was inserted.
