    Study Notes

    Immediate Denture

    • An immediate denture is a complete or removable partial denture fabricated to be placed immediately after natural teeth are extracted.
    • It is constructed before tooth extraction and positioned after the natural teeth are removed.
    • Compatibility with oral tissues is crucial.
    • It restores masticatory function within limits.
    • It must harmonize with speech, respiration, and swallowing.
    • Aesthetically acceptable design is necessary.
    • Preservation of existing tissues is important.

    Advantages

    • Maintains appearance.
    • Preserves masticatory movement patterns of the mandible.
    • Maintains maxillomandibular relations.
    • Tooth selection and arrangement is easily duplicated.
    • Superior neuromuscular control of dentures.
    • Better denture foundations.
    • Prevents tooth movement.
    • Minimal interference with speech.
    • Shorter learning period.
    • Protection from trauma.
    • Acts as a stent, controls bleeding, and aids healing. Usually causes less pain.

    Disadvantages

    • More chair time and additional appointments, increasing costs.
    • Less accurate fit and less retention.
    • No anterior try-in.
    • Increased patient discomfort.
    • More postoperative care.
    • Not suitable for all patients.

    Indications & Contraindications

    Indications

    • Multiple extractions.
    • Aesthetics.
    • Function.
    • Conventional complete dentures are contraindicated.

    Contraindications

    • Patients with debilitated diseases.
    • Patients for whom multiple extractions might be unwise due to systemic conditions, such as hemophilia.
    • Patients who have undergone radiation therapy.
    • Indifferent or hysterical patients.
    • Patients with poor oral hygiene.

    Types

    Partial Immediate Denture (PID)

    • Socketed (PID): no flange.
    • Flanged (PID): without alveoloplasty; with alveoloplasty.

    Complete Immediate Denture (CID)

    • One-step (Interim CID).
    • Two-steps (Conventional CID).

    Partial Immediate Denture (Socketed)

    • Artificial teeth are placed in extracted tooth sockets, without a labial flange.
    • Indications include deep labial or buccal undercuts, high lip line, and minimal surgical intervention is desirable.
    • Contraindications include periodontal disease with bone loss (difficulty in aesthetics) or lower dentures due to poor retention.

    Partial Immediate Denture (Flanged)

    • Used in cases of alveolar bone loss due to periodontal disease.
    • Indications include periodontally involved teeth with bone loss, no anterior undercuts, using the flange as a surgical splint, normal lip.
    • Contraindications include undercuts in the anterior labial region of the ridge, and active lips.

    Advantages of Flanged

    • Strong retention and support.
    • Fast healing with smooth ridges.
    • Relining is easy.

    Disadvantages of Flanged

    • Flange may cause labial fullness; poor aesthetics.
    • Flange border may traumatize mucosa (often thin).

    Technique of Flanged

    • Stone teeth are removed. The ridge is contoured to resemble the ideal ridge.
    • With alveoloplasty, upper alveolar process protrusion can be improved, alveolar bone reshaped at extraction time. The ridge is trimmed and shaped.
    • A surgical template is then constructed on the modified cast as a guide for shaping the alveolar process.

    Complete Immediate Denture (One-step- Interim)

    • Used for a short period, as a temporary prosthesis for aesthetics, mastication, occlusal support, and convenience.
    • Placed at the same appointment as tooth extraction.
    • Worn during healing period until more definitive prosthetic therapy is available.
    • Extraction of teeth from both the anterior and posterior done in one visit
    • Appropriate if anterior teeth cause pain or looseness or patient wants fewer visits
    • Should only be used if patient can be treated in hospital.
    • Necessary record-keeping includes preliminary records, mouth preparation (scaling and curettage), clinical and laboratory procedures, jaw relation records, tooth setup and try in, and post-insertion care.

    Complete Immediate Denture (Two-Step- Conventional)

    • Constructed two months after extraction of posterior teeth; anterior teeth extracted and denture inserted at the same time.
    • Two-stage surgical approach: posterior teeth extracted, leaving only opposing posterior centric stops; maintain vertical dimension.
    • Post-extraction healing, posterior jaw relation set, then plaster anterior teeth are broken from the cast.
    • Preparation of complete immediate denture follows.

    Procedure for Construction

    • Alginate impressions of both jaws are taken.
    • Resulting casts are mounted on an articulator using interocclusal wax record.
    • Cast duplication is done (reference when setting teeth).
    • The teeth are removed from the casts, ridges are trimmed, acrylic templates fabricated.
    • Artificial teeth are placed, the denture cured, and finished with a normal flange.
    • In hospitals, teeth removal, ridge trimming, and denture insertion use templates.

    Jaw Relation

    • The lower natural teeth guide establishing the heights of the occlusal plane of the wax rim.
    • Face bow record created to mount the upper cast.
    • Centric relation records complete articulator mounting.

    Selection of Teeth

    • The presence of remaining natural teeth facilitates the selection process.
    • Posterior teeth are arranged.
    • Try-in is to verify the arrangement of the posterior teeth.

    Modification of Master Cast

    • Techniques for simple extractions without alveoloplasty: remaining anterior stone teeth are removed; residual ridge is contoured to conform to post-surgical contours.
    • Denture type dictates the preparation.

    Modification of Master Cast (Alveoloplasty)

    • Master cast is modified by cutting off the teeth and trimming part of labioalveolar bone to eliminate undercuts or protrusion
    • Duplicate edentulous cast to produce clear acrylic template, used as a guide during surgery to measure amount of bone to contour.

    Other Procedures

    • Selected teeth are placed and securely waxed to the trial denture base.
    • Denture construction involves processing, laboratory remounting to eliminate occlusal errors, finishing, and polishing.
    • Tooth extraction is followed by ridge contouring (alveoloplasty); typically in patients with maxillary protrusion, deep undercuts.
    • Immediate complete denture is placed.
    • Clinically, impressions, labial impressions, and jaw relation included.
    • Lab work includes pouring impression, mounting casts (articulator), preparing the cast, arranging teeth, and processing the denture.
