Maxillofacial prosthetics.

Investigations are continuing in methods to preserve the dentition and to improve the quality of tissues for the patient receiving radiation to the head and neck. Increased knowledge related to obstructive sleep apnea presents the prosthodontist with an opportunity to provide support during the treatment of these patients. Advances in implant prosthodontics have increased our capability to rehabilitate the patient with intraoral or facial defects. Advances have been made in the use of light-cured materials as well as in the utilization of microwave energy to fabricate prostheses. Unfortunately, the ideal material to be used as a soft liner or for maxillofacial restoration continues to elude the profession.

The effect of bonding agents on the bond strengths of facial silicone elastomers to a visible light-activated resin.

Three bonding agents were evaluated to determine their effect on the strength of the bond when Silskin II and Cosmesil SM4 silicone facial elastomers were polymerized to a light-activated denture resin. A silane bonding agent proved to be superior, whereas a light-activated bonding agent had inferior bonding characteristics. Intensive heat aging had no significant effect on bond strength.

Mushroom-shaped resilient retainer for maxillary obturator prostheses.

A new type of highly resilient retainer for maxillary obturator prostheses is described. The obturator component is composed of an acrylic resin connector and a round resilient wing, with the combined shape resembling a mushroom. The retainer is designed to absorb mechanical stresses, which are transmitted from the denture portion to nasal soft tissues through the obturator extension, and to use tissue undercuts more effectively than do conventional hollow extension prostheses. Renewability of the retainer part is another advantage of this retainer. From these properties, the retainer seems to have many indications for the prosthodontic treatment of maxillary defects.

[A new implant system for the fixation of facial prostheses].

A newly developed titanium implant system is useful for the fixation of facial prostheses. Due to the osteointegration of this material the system can also be used for the treatment of anatomically less favorable cases. The clinical results achieved to date are good.

A smoking cessation intervention for head and neck cancer patients: trial design, patient accrual, and characteristics.

This paper describes the aims, study design, and patient accrual and characteristics from an ongoing randomized controlled trial evaluating a surgeon- and dentist-delivered smoking cessation intervention for head and neck cancer patients. Subjects (n = 186) accrued into the trial are profiled in terms of demographics, medical and treatment descriptors, smoking history and behavior at enrollment, and related psychosocial variables (mood, adherence indicators, and alcohol consumption). These patients have long histories of tobacco use, moderate to high levels of nicotine dependence, and a lack of overt mood disturbance and are receptive to behavioral change.

[Multidisciplinary patient care in facial prosthetics].

The aim of maxillofacial prosthetics is the treatment of patients with head and neck diseases in a multidisciplinary way. The treatment of patients with a facial defect should be based on a close cooperation between maxillofacial prosthetist and MFP technician. The rehabilitation process and the specific role of each is described.

Resilient acrylic resin template for facial prostheses.

Clay or wax is used extensively as a modeling material for trial facial prostheses. This article describes a technique that uses a resilient acrylic resin as a matrix to lodge the ocular component and wax as the sculpturing medium for orbital prostheses. The technique can be adapted and used for all facial prostheses.

[Possible applications of a method for 3D reconstruction of CT image data. OP-planning, finishing of individual alloplastic implants for replacement of cranial and maxillofacial bone structures].

A method for the three-dimensional reconstruction of CT-image data permits manufacturing of natural size anatomical models thus enabling preoperative measurements of relevant parameters (length, areas, and volumes). The methods described allow for new perspectives in preoperative planning of dental implants, particularly for the maxillary problem area. The use of 3D image data for manufacturing individual alloplastic implants simplifies the exact reconstruction of symmetrical bone structures, which up to now was impossible to achieve with conventional methods. Applications in the fields of orthodontic surgery and in neurological surgery are suggested. Refinement of available techniques is possible by means of additional segmentation of soft tissues, and by implementation of more sophisticated software for better visualisation and smoothly shaped surfaces. Future applications may even include aesthetic surgery.
