Nasal floor elevation combined with dental implant placement

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Regenerative Medicine

Background:

• Alveolar bone height deficiency in the anterior region often precludes standard dental implant placement.
• Nasal floor elevation is a surgical technique to augment bone in the maxillary anterior region.

Purpose of the Study:

• To evaluate the survival rate of dental implants placed simultaneously with nasal floor elevation.
• To assess the predictability and outcomes of this combined surgical approach.

Main Methods:

• A retrospective cohort study of 32 patients who received 100 dental implants with concurrent nasal floor elevation.
• Pre-operative computed tomography (CT) scans were used to measure available bone height.
• Data collected included implant dimensions, bone augmentation achieved, and implant survival at follow-up.

Main Results:

• The average pre-operative bone height was 9.1 mm, with an average bone addition of 3.4 mm following nasal floor augmentation.
• The mean follow-up period was 27.8 months.
• A 100% implant survival rate was recorded, with no implant failures observed.

Conclusions:

• Nasal floor elevation is a predictable procedure for placing dental implants in severely atrophic jaws.
• The technique offers increased implant stability through bicortical support.
• This approach successfully addresses bone deficiencies for dental implant restoration.
