Abstract
Fixed partial dentures with an ovate pontic design contacting the underlying soft tissue may interfere with long-term mucosal health. The purpose of this study was to examine the clinical and histologic characteristics of the human alveolar ridge mucosa adjacent to an ovate pontic-designed restoration. Twelve patients requiring maxillary fixed partial dentures (either implant- or tooth-supported) with a pontic site in the premolar or molar region were studied. The pontics had an ovate design and were adapted to the underlying mucosa with tight but noncompressive contact. Patients used Super Floss once a day to clean the infrapontic area. After 12 months, soft tissue biopsy specimens about 3 x 3 mm in size were obtained (1) from the ridge mucosa in contact with the pontic (test site) and (2) from an adjacent uncovered masticatory mucosal area (control site). Histometrically, the thickness of the epithelium and the keratin layer and the height of the connective tissue papillae were measured. Morphometrically, the composition of the connective tissue of the specimens was analyzed in a 200-microm-wide zone immediately subjacent to the epithelium (zone A) and in a 200-microm-wide central connective tissue portion (zone B). A point-counting procedure was used to calculate the relative proportions occupied by collagen, fibroblasts, vascular structures, inflammatory cells, and residual tissue. Differences between the tissue fractions in test and control sites were analyzed with the Wilcoxon signed rank test (.05 level of significance). At 12 months, only 3 pontic sites showed clinical signs of mild inflammation, whereas the other test sites and all control sites appeared healthy. A thinner keratin layer was observed in pontic sites than in control sites (8 microm vs 22 microm). Larger tissue fractions of inflammatory cells were found in pontic sites than in control areas in the zone immediately subjacent to the epithelium. Within the limitations of this study, restoring an edentulous space with an ovate pontic supported by adequate oral hygiene measures was not associated with overt clinical signs of inflammation. Histologically, however, this pontic design was associated with a thinner keratin layer and with changes in the composition of the connective tissue compartment subjacent to the epithelium.
What is a complicated crown fracture?
Complicated crown fractures are defined as fractures involving enamel and dentin with pulp exposure. These injuries produce changes in the exposed pulp tissues, and a biological and functional restoration represents an important clinical challenge.
What is the difference between a complicated tooth fracture and an uncomplicated tooth fracture?
The difference between an uncomplicated and a complicated crown fracture is how deep the fracture goes. An uncomplicated crown fracture will involve the enamel and the dentin layers of a tooth. It does not involve any exposure of the pulp. The complicated fracture will also involve exposure of the pulp.
How do you treat a horizontal root fracture?
In several studies it is reported that a slightly flexible fixation is the best treatment to obtain a natural healing and to preserve pulpal vitality [10, 35]. In middle root fracture the ideal splinting period to achieve a good healing and to gain a long term stability of the fragment is 3-4 weeks [21].
What are the types of crown fractures?
Andreasen has classified crown fractures as enamel infractions, enamel fractures with little or no dentin involvement, enamel–dentin fractures with no pulp involvement (uncomplicated crown fractures), and enamel–dentin fractures with pulpal involvement (complicated crown fractures).
What are symptoms of a complicated fracture?
Symptoms
- A visibly out-of-place or misshapen limb or joint.
- Swelling, bruising, or bleeding.
- Intense pain.
- Numbness and tingling.
- Broken skin with bone protruding.
- Limited mobility or inability to move a limb or put weight on the leg.
Does a complicated tooth fracture bleed?
In complicated fractures, the tooth's pulp cavity is exposed and its root compromised. Bleeding and pain may result. Chronic pain is typically the most significant effect. Exposure of the pulp makes the teeth susceptible to serious infection, pulp necrosis (dead tissue) and painful abscesses of these tooth roots.
What type of tooth fracture has a better prognosis?
In conclusion, teeth with horizontal root fracture have a better prognosis compared with teeth with vertical root fracture in patients undergoing periodontal maintenance.
What is the difference between a complicated tooth fracture and an uncomplicated tooth fracture?
The difference between an uncomplicated and a complicated crown fracture is how deep the fracture goes. An uncomplicated crown fracture will involve the enamel and the dentin layers of a tooth. It does not involve any exposure of the pulp. The complicated fracture will also involve exposure of the pulp.

What type of tooth fracture has a better prognosis?
In conclusion, teeth with horizontal root fracture have a better prognosis compared with teeth with vertical root fracture in patients undergoing periodontal maintenance.
What is the difference between compound fracture and complicated fracture?
Simple fractures are normally treated with the use of a cast or splint, which keeps the broken bone stabilized in the correct place to allow it to heal naturally. Compound fractures require more intensive treatment. Usually, surgery will be required so that doctors can place the fractured bones back into position.
Which root fracture has the best prognosis?
Apical fractures have the best prognosis, and then midroot, and then coronal.
Can a tooth root fracture be repaired?
Even with the loss of the fractured crown the root often can be restored with the assistance of the modern techniques of extrusion or periodontal surgery. The prognosis for tooth survival following a horizontal root fracture can be summarized as quite good.
What is the treatment for maxillary fracture?
Maxillary (Le Fort) fracture: Open reduction with internal fixation is the standard. If CSF rhinorrhea is present, a neurosurgeon should be consulted. Prophylactic antibiotics are warranted if the fracture extends through the tooth-bearing region or through the nasal or sinus mucosa.
Can a fractured crown be repaired?
Dentists can repair damaged crowns with composite resin in certain cases. However, if the damage is too severe or if they are not properly equipped to restore the crown, then a new crown may need to be installed.

Basilar skull fracture.
This is the most serious type of skull fracture, and involves a break in the bone at the base of the skull.
What bone fractures are most difficult to repair?
Example: A comminuted fracture is the most difficult to repair due to the bone having fractured into numerous pieces. Multiple bone pieces require more effort to hold them together in the ideal position for healing.
Can a fracture be fixed without surgery?
How are fractures treated without surgery? Whether surgery is needed or not, every fracture heals by immobilizing the bone and giving it time to reconnect and strengthen. Immobilization can be done with a boot, a splint, a cast, or a brace depending on where the fracture occurs and how severe it is.
What is considered a complex fracture?
According to Natalie Casemyr, MD, assistant professor of Orthopaedics & Rehabilitation at Yale Medicine, fractures are labeled “complex” when the bone breaks into bits and pieces, when the soft tissue surrounding the bone is severely damaged, or when the patient has other illnesses or injuries that complicate treatment ...
What is the most serious complication of fracture
Pulmonary embolism is the most common severe complication of serious fractures of the hip or pelvis. It occurs when a blood clot forms in a vein, breaks off (becoming an embolus), travels to a lung, and blocks an artery there. As a result, the body may not get enough oxygen.
Compound Fracture
This is one of the most severe injuries: A compound or open fracture is when the bone pierces the skin when it breaks. Surgery is usually called for due to its severity and the risk of infection.
What causes a complicated fracture?
Some of the most common causes are car accidents and falls from a great height, like off a ladder or roof. Any impact to your bones can cause a comminuted fracture. However, slips, falls and other common causes of broken bones aren't usually strong enough damage to your bones enough to cause a comminuted fracture.
Does a fractured tooth need extraction?
A fractured tooth must be removed as carefully as possible in order to preserve the integrity of the surrounding bone. Sometimes, the surrounding bone becomes damaged as a result of the traumatized tooth, in which case additional procedures such as bone grafting or recontouring may be necessary.
