Palatal Obturator - Dental Implant Dentist Cost
Fabrication of an obturator prosthesis using dental implants to retain and support the prothesis for a cancer patient.
The Obturator Prosthetic — MAXILLECTOMY
A definitive obturator is not indicated until the surgical site is healed and dimensionally stable and the patient is prepared physically and emotionally for the restorative care that maybe necessary. Changes associated with healing and remodeling will continue to occur in the border areas of the defect for at least one year. Dimensional changes are primarily related to the peripheral soft tissues rather than to bony support areas.[,,]
Replacing any part of maxilla-facial region with prosthesis puts a great responsibility on the specialist to use his experience and knowledge for fabrication of prosthesis which is customized to the individual’s need so as to improve his confidence and thus quality of life. Though it is difficult to improve the quality of life for hemimaxillectomy patients compared with patients with conventional prostheses, this can be achieved with skill, knowledge, and experience of specialists. With constant advent in technology there is coordinated improvement in quality of prosthesis and its clinical servability. The new generations of magnets with improved technology provide sufficient denture retention for clinical application. This case highlights on better management of compromised mouth opening cases however longitudinal studies with larger population are needed to ascertain the success of such prosthesis on a long run and patient’s acceptance for the same. However, further follow-up may be necessary to ascertain the long-term usefulness of the magnet-retained obturator prosthesis, because loss of magnetism can occur because of corrosion.
Maxillofacial Prosthetics - Implant Retained Maxillary Obturators
The type of palatal obturator, we now use, is defined as "self-stabilizing" by J. Dichamp and has a silicon portion which adapts perfectly to the maxillectomy and a device on the opposite surface which anchors the dentures in acrylic resin . The layer of silicon closes the defect also in the absence of a prosthesis, thereby permitting the defect to be closed and sealed immediately. A grooved anchoring system gives maximum retention to the prosthesis even if there is no remaining dentition or underlying support. The obturator, in silicon, does not give rise to problems of deformation or growth of fungus on the surface for at least 3 years.
A lateral scar band results after surgical resection at about the level of the mucobuccal fold. Because of its lack of bone support, the lateral scar band also tends to stretch with continued use. This stretching may necessitate sequential additions to the prosthesis which maybe limited by cosmetic requirements and size and weight of the prosthesis. The height of the lateral wall of defect can be utilized for indirect retention. A high lateral wall of an obturator will undergo less vertical displacement with a given defect wall flexure than will a shorter prosthesis lateral wall.

Later, the patient was fitted with a partially hollow palatal obturator of a self-stabilising type, comprising three reciprocally stable parts, allowing separation of the oral and nasal cavities also in the absence of a prosthesis with dentures (Fig. ).
9. What do I use to heat the obturator?
You can use the ThermaPrep® oven but you must use the minimum heating time and take out the obturator as soon as you hear the first beep.

The weight of the obturator can act as a dislocating force, hence the prosthesis should be as light as possible.

The temporary obturator is constructed from the postsurgical impression cast which has an artificial palate and artificial ridge and generally has no teeth. The closed bulb extending into the defect area is hollow. The patient is usually seen every two weeks becau se of the rapid soft tissue changes that occur within the defect during the organization and healing of the wound. The new lining material is placed or changed. It is best to remove the entire old interim lining material because of porosity, leading to bacterial contamination and precipitation of undesirable odors and mucosal irritations. The periodic addition of interim lining material increases the bulk and weight of the obturator and this temporary material may become rough and unhygienic.
edentulous mouth is referred to as an obturator
Approximately six months after surgery, consideration maybe given to the construction of a definitive obturator prosthesis. It is constructed from the postsurgical maxillary cast. This obturator has a metal framework which acts as the palate and supports the teeth and the closed bulb which is hollow. Often the temporary obturator will need to function comfortably for as long as six months. The timing will vary depending on the size of the defect, the progress of healing, the prognosis for control of the tumor, the effectiveness of the present obturator, and the presence or absence of teeth. To reduce and improve adhesion and retention, a hollow obturator bulb is required for cleft palate prostheses and for dentures following maxillectomies.

1. What does “crosslinked” mean?
GuttaCore is the first obturator with a crosslinked gutta-percha core. Crosslinking is a well-established scientific process that connects the polymer chains and transforms the gutta-percha to stabilise the structure, while keeping its best features. The crosslinked gutta-percha core retains its shape when heated - and easily removes. Gray radiopacifiers are added for improved radiographic appearance.

It is a base plate appliance which is constructed from the preoperative impression cast and inserted at the timeof resection of the maxilla in the operating room. The surgical obturator provides a matrix on which the surgical packing can be placed. It maintains the packing in the proper relationship, thus ensuring close adaptation of the skin graft. It also reduces oral contamination of the wound during the immediate postsurgical period and may thus reduce the incidence of local infection, and the nasogastric tube maybe removed at an earlier date.
