Frenal attachments consist of thin bands of
fibrous tissue attached to the bone. If the
frenum is close to the crest of the alveolar
ridge, it can interfere with the extension of
the denture flange and, consequently, with Read the rest of this entry »

The goal of a vestibuloplasty is to remove
unwanted muscle insertions into the alveolar
ridge. This is done by exposing bone at the
place where these muscles formerly attached.
The vestibuloplasty surgical technique requires
an adequate amount (height) of alveolar
bone. The basic problem here is usually
not the lack of bone but rather that the shallow Read the rest of this entry »

Papillary hyperplasia or denture stomatitis is
generally secondary to ill-fitting dentures.
Other factors that contribute to this condition
are poor oral hygiene, fungal infections,
and around-the-clock denture use.
This condition is not premalignant but
inflammatory in nature, and total fullthickness
removal of the mucosa is not
needed. Before performing invasive surgical Read the rest of this entry »

Epulis fissuratum is a hyperplastic growth of
the mucosa secondary to denture irritation.
This constant irritation eventually develops
submucosal fibrosis. This condition interferes
with denture stability and comfort. Patients
usually see great benefit from surgical
treatment. However, before surgery either
the patient should discontinue wearing the
denture for two weeks or the dentist should Read the rest of this entry »

Mandibular tori are usually bilateral and located
on the lingual aspect of the mandible.
They are normally found in the premolar
and molar area. Before construction of a
mandibular removable denture, they frequently
need to be removed. The mucosa
covering them is thin and prone to irritation
and ulceration. Read the rest of this entry »

A maxillary torus consists of a sessile mass of
cortical bone in the middle of the palate.
Most often, maxillary tori do not need surgical
removal. Satisfactory dentures can be
constructed over most of them. However,
there are some situations where their removal
is indicated:
• Constant trauma Read the rest of this entry »

A maxillary tuberosity can increase in the
vertical dimension, decreasing the vertical
space between the maxilla and the mandible.
The resultant problem is not having enough
space for the denture base. To determine
adequacy of the space, a dental mirror
should be placed between the tuberosity and
the ascending ramus of the mandible. If it Read the rest of this entry »

Patients who are partially or completely
edentulous will have esthetic and biomechanical
concerns that need to be addressed
before prostheses can be fabricated. The rehabilitative
goal of an edentulous patient is
to restore oral function and facial form.
Approximately 10 percent of the American Read the rest of this entry »

Jaw fractures, although uncommon, can
complicate impacted third molar surgery.
The clinician must be cognizant of the factors
listed here, as these could predispose this
unfortunate complication: difficult (deeply
impacted teeth) extractions, older-age patients,
atrophic jaws, systemic disease affecting
bones (for example, osteoporosis), associated Read the rest of this entry »

The phenomenon of alveolar osteitis, otherwise
known as dry socket, has been attributed
to multiple factors including smoking,
difficulty of extraction, bacterial contamination,
birth control pills, and aberrant host
healing. These predisposing factors may or
may not be present. In any given case, it is
difficult to determine the cause. Simple extractions Read the rest of this entry »
