Guided bone regeneration for horizontal and vertical ridge augmentation in the anterior maxilla

Situation

Patient Information

- Patient: 50 year old patient

- Medical history: well controlled hypertension, non smoker


Pre-operative Observation

- Initial situation with a high lip position (left), Intra oral view of the area (right)

- Missing tooth on #21

- Periodontal disease

- Mobility grade 3 on #11 and #12


Treatment Planning

- Extraction of #12 and #11

- Horizontal and vertical augmentation of the anterior maxilla with a GBR procedure

- Implant placement into the augmented ridge of site 11 and 12 in four months

 

The site exposed by rising a trapezoidal flap

The autologous bone was harvested in the cortical of mandibular area with ACM bone collector from Neobiotech, the autologous was soaked in blood and mixed with DBBM.

DBBM and autologous bone packed into the defect around the tenting screw in a slightly over contoured fashion, a resorbable membrane was used to separate the tissue compartment made up of bone from the overlying soft tissue

Tension free Primary wound closure.

Second procedure after 4 months.
