Study Notes

Definitions and Advantages of Immediate Dentures

Immediate dentures are completely constructed before tooth extraction and inserted immediately afterward.
They can be complete dentures (full arch) or partial dentures (RPD).
Advantages include maintaining appearance, preventing jaw relationship changes, reduced postoperative pain, and preserving a normal lifestyle during recovery.
Immediate dentures can reduce residual ridge resorption and help maintain oral support.

Disadvantages of Immediate Dentures

Increased complexity of clinical procedures.
Inability to try out anterior teeth for aesthetics or phonetics.
Increased treatment cost.
Frequent relines, rebases, or remakes needed.
Increased patient discomfort during the healing phase.

Indications for Immediate Dentures

Unrestorable remaining teeth (caries, periodontal disease).
Patients requiring daily social activities.
Patients with stable health conditions
Patients who accept potential cost increases.
Patient's desire to maintain appearance and health.

Contraindications for Immediate Dentures

Patients with poor surgical risks due to underlying health conditions, such as cardiovascular diseases.
Patients with active infections needing surgical drainage.
Patients with limited mental capacity or emotional disturbance.
Patients who have undergone radiation therapy.

Types of Immediate Dentures

Interim Dentures: Temporary dentures to replace lost teeth until a complete denture is made.
Transitional Dentures: Temporary full or partial dentures constructed while some natural teeth remain, eventually serving as a transitional complete denture.
Conventional Complete Dentures: Made completely after extraction of all teeth.
Definitive Cast Partial Dentures: Complete partial dentures after extraction
Diagnostic Immediate Dentures: To diagnose a patient's problem.
Immediate Dentures without Surgery: Socket-type or Flanged dentures constructed without alveoloplasty.

Procedures for Construction and Care

Preliminary Impressions: Critical to determine interarch relationships for occlusal rims
Selection of Teeth: Natural tooth locations help with duplicating structures.
Arrangement of Anterior Teeth: Aesthetic and functional alignment is crucial.
Two-step Construction: Posterior teeth are extracted first, then anterior teeth are extracted and the denture is inserted.
Immediate dentures require precise surgical techniques and require follow-up care for relines, rebases, and remakes.

Surgical Considerations

Extraction Techniques: Surgical procedures (e.g. alveoloplasty) tailored for socket preparation, tissue conditioning, and managing swelling
Post-extraction care: Precise instructions and a schedule for wound care, pain management, and denture use are crucial.
