Single Midline Implant in the Edentulous Mandible Without Augmentation
In July 2006, a 66-year-old edentulous woman received new complete dentures in both the maxilla and mandible at the Department of Prosthodontics, Propaedeutics and Dental Materials (University of Kiel, Germany). Both dentures had a perfect fit and met high dental standards. To reduce the risk of fracture of the mandibular denture, it was reinforced with a mesh CoCr framework.

General Risk Assessment
Patient-related Factors
| Oral hygiene | Fair |
|---|---|
| Compliance | Adequate |
Patient-medical Factors
| Medical Fitness | Healthy, able to undergo planned anesthesia and surgical procedure (ASA I) |
|---|---|
| Medications | No medications that would negatively affect the surgical procedure and outcomes. |
| Radiation Treatment | None |
| Growth Status | Complete |
Site-related Factors
| Access | Adequate |
|---|---|
| Pathology near the implant site | None |
| Previous surgeries in planned implant site | No previous procedures. |
Surgical Classification
Surgical Complexity
| Timing of placement | Healed (Type IV) |
|---|---|
| Simultaneous or Staged grafting procedures | Implant placement without adjunctive procedures |
| Number of implants | One |
Anatomy
| Keratinized Tissue | Sufficient (>4 mm) |
|---|---|
| Soft Tissue Quality | No scars or inflammation |
| Proximity to vital anatomic structures | Minimal risk of involvement |
Prosthodontic Classification
Complicating Factors
| Biological | Screw-retained restorations with appropriate contours |
|---|---|
| Mechanical/Technical | Absence of contributing factors |
| Planned contour of tissue-fitting surfaces | Appropriate contours (hygienic - accessible for maintenance) |
Prosthesis Factors
| Prosthetic volume | Adequate. Space available for ideal anatomy of the restoration |
|---|---|
| Inter-occlusal space | Compromised. Can be resolved without adjunctive therapy |
Occlusal Factors
| Occlusal scheme | User-defined occlusal scheme achievable |
|---|---|
| Involvement in occlusion | Involvement |
| Occlusal parafunction | Absent |
Complexity
| Loading Protocol | Early/Conventional |
|---|---|
| Interim prosthesis | Tissue or interim implant supported |
| Number of implants | One |
| Timing of placement | Healed (Type IV) |
Esthetic Risk Assessment
Edentulous Esthetic Risk Assessment (removable)
| Facial Support | Desired tooth position provides sastifactory labial support |
|---|---|
| Labial Support | Flange provides required lip support |
| Maxillomandibular Relationship | Class I |
