2. Materials and Methods
2.1. Patient Enrolment
- Complete edentulism (minimum duration of 6 months);
- Interforaminal bone dimension of at least 4 mm clinical width (clinical examination with a periodontal probe) and a minimum height of approximately 13 mm (assessed by two-dimensional X-ray examination);
- Bone augmentation required for standard diameter implant placement;
- Good general health (ASA classification 1 or 2);
- Not dependent on care.
2.2. Study Procedures
2.3. Outcome Measures
2.3.1. Radiographic Analysis of Peri-Implant Bone Levels
2.3.2. Clinical Parameters
- mPI: modified Plaque Index [27];
- PPD: peri-implant probing pocket depth: measured to the nearest millimeter with a Hu-Friedy PGF–GFS periodontal probe (Hu-Friedy, Chicago, IL, USA);
- The occurrence of subsequent bleeding (yes/no);
- The presence of KM at the lingual and buccal aspects.
- Matrix loosening;
- Denture cracking and fractures;
- The need for relining;
- Any signs of wear at the male part.
