IMMEDIATE DENTURES The decision may be _lWde to insert dentures at the time of tooth removal and bony recontouring. Hartwelll-‘ cites several advantages of an immediate denture technique. The insertion of a denture after extraction offers immedi-ate psychologic and esthetic benefits to patients, whereas alternatively they may De edentulous for some time. The immedia-te insertion of a denture after surger

labial Frenectomy

labial Frenectomy Labial frenal attachments consi t of thin bands of fibrou tissue covered with mucosa, extending from the lip and cheek to the alveolar periosteum. The level of frenal attachments may vary. from the height of the vestibule to the crest of the alveolar ridge and evert to the Incisal papilla area in the anterior maxilla. With the exception of the midline labial frenumr association with a diastem

Inflammatory Papiilary Hyperplasia of the Palate

Inflammatory Papiilary Hyperplasia of the Palate Inflammatory papillary hyperplastic tissue formation in the palate is  frequently a result of mechanical irritation and is seen most often in patients who wear prosthetic appliances. Other potential contributing factors to thispsocess include poor hygiene, fungal infections, and the associated  nflamrr.ation. This condition usually appears as multiple nodula p

Inflammatory Fibrous Hyperplasia

Inflammatory Fibrous Hyperplasia Inflammatory fibrous hyperplasia, also called epulis fissuratum  or denture fibrosis, is a generalized hyperplastic enlargement of mucosa and fibrous tissue in the alveolar ridge and vestibular area, which most often results from ill-fitting dentures.’ In the early stages of fibrous hyperplasia, when fibrosis is minimal, nonsurgical treatment with a denture in combination

Unsupported Hypermobile Tissue

Unsupported Hypermobile Tissue Excessive hypermobile tissue without inflammation on  he. alveolar ridge is generally the result of resorption of the underlying bone, ill-fitting dentures, or both. Before the excision of this tissue,·a determin tion must be made of whether the underlying bone sho~ld be augmented with a graft. If a bony deficiency is the primary cause of. soft tissue excess, then. augmentation

Lateral.Palatal Soft Tissue Excess

Lateral.Palatal Soft Tissue Excess Soft tissue excess on- the lateral aspect of the palatal vault often interferes with proper construction of the denture As with bony abnormalities of this area, soft tissue hypertrophy often narrows the palatal vault and creates slight undercuts, which interfere with denture. construction and insertion. One technique suggested for removal of-lateral palatal soft tissue invo

Mandibular Retromolar Pad Reduction

Mandibular Retromolar Pad Reduction The need for removal of mandibular retromolar hypertrophic tissue israre. It is important to determine that thepatient is not posturing the  andible forward or vertlcal- Iy ovcrcloscd during clinical evaluation and with treat-: mcnt recor ds and mounted .casts. Local anesthetic infiltration in the area requiring excision is sufficient. An elliptic incision is made to excise

Maxillary Tuberosity Reduction (Soft Tissue)

Maxillary Tuberosity Reduction (Soft Tissue) The primary objective of soft tissue maxillary tuberosity  reduction is to provide adequate interarch space for proper denture construction in the posterior area and a firm mucosal base of consistent thickness over the alveolar ridge denture-bearing area. Maxillary tuberosity reduc-‘ tion may require the removal of soft tissue and bone to achieve the desired


SOFT TISSUE ABNORMALlTIES Abnormalities of the soft tissue in the denture-bearing and peripheral tissue areas include excessive fibrous or hypermobile tissue; inflammatory lesions; such as inflammatory fibrous hyperplasia of the vestibule and inflammatory papillary hyperplasia of the palate; and abnormal muscular and frenal attachments. With the exception of pathologic and inflammatory lesions, many of the ot

Mandibular Tori

Mandibular Tori Mandibular tori are bony protuberances on the lingual  spect of the  andible that usually occur in the premolar area. The orlgtns of this bony exostosis are uncertain, and the growths may slowly increase in size. Occasionally, extremely large tori interfere with normal speech or tongue function during eating, but, these tori rarely require removal when teeth are present: Afterthe removal, of
