Immediate loading implants: a clinical report of 1301 implants

Area of Science:

• Dentistry
• Oral Surgery
• Biomaterials

Background:

• Traditional dental implant techniques often involve a submersion period for osseointegration.
• Immediate loading protocols offer potential benefits but require careful patient and technique selection.
• Achieving implant stability is crucial for successful osseointegration and functional restoration.

Purpose of the Study:

• To present four immediate loading implant techniques as alternatives or complements to the conventional submersion method.
• To evaluate the long-term success rates of different immediate loading prosthodontic approaches.
• To provide guidelines for selecting appropriate immediate loading implant strategies.

Main Methods:

• A retrospective study involving 1301 implants placed in 153 maxillary and 309 mandibular arches.
• Immediate loading with provisional prostheses (wings, plastic, plastic with metal frame) and intraoral welding for implants with primary retention.
• Long-term follow-up over 21 years to assess success rates.

Main Results:

• Success rates varied by technique: intraoral welding (99.3%), provisional prosthesis with metal frame (98.3%), metal wings (97.9%), and provisional plastic prosthesis (88.02%).
• Early results with provisional plastic prostheses were lower, reflecting limitations in available technology (1974-1984).
• Factors influencing outcomes included facial morphology, occlusion, tongue function, bone density, and implant characteristics.

Conclusions:

• The evaluated immediate loading techniques demonstrate high long-term success rates, particularly intraoral welding and provisional prostheses with metal frames.
• Careful consideration of patient-specific factors and appropriate technique selection are essential for successful immediate implant loading.
• The study proposes guidelines to aid clinicians in implementing immediate loading protocols effectively.
