Maxillofacial Prosthetics

What is Maxillofacial Prosthetics and Prosthodontics ?

Maxillofacial Prosthetics and Prosthodontics is a specialty of dentistry which deals with the rehabilitation of patients with acquired and congenital defects of the head and neck region. These range from minor to major functional disabilities combined with cosmetic disfigurement.

Therapeuo as a centre for Maxillofacial Prosthodontics and Prosthetics

  •  Rehabilitation of patients with head and neck disabilities is difficult and requires close interactions among several health science disciplines. The Maxillofacial Prosthodontist is the primary person involved in many facets of patient care, and is therefore the individual who is in the best position to coordinate the efforts required in this complex rehabilitative process. Members of the team include oral and maxillofacial surgeons, plastic surgeons, radiologists, oncologists, head and neck surgeons, neurosurgeons, otolaryngologists, periodontists, orthodontists, social workers, speech therapists, occupational therapists, among others. Our team is one that can bring together the needed specialists to evaluate and treat these patients, including our on-site maxillofacial prosthodontist.

Objectives of our Centre

  •  The fundamental objective of our Centre is to provide prosthodontic reconstruction for those patients with orofacial defects resulting from birth defects, trauma, or following treatment for head and neck cancers. Defects of this type can lead to altered function and an inability to participate in normal activities, which has a negative impact on the patient's psychosocial behaviour. The Centre also addresses the need for a focal point for the education of medical, dental, and auxiliary dental health personnel.

Birth Defects

  •  Craniofacial deformities such as cleft lip, cleft palate are managed by specialized teams of doctors and allied health professionals. The role of the maxillofacial prosthodontist is critically important in supporting the surgical care in such patients when closures of the openings between the nasal and oral cavities are achieved, or providing supporting structures for swallowing, chewing, and speech.

Trauma

  •  Injuries resulting from motor vehicle, industrial and residential accidents, and gunshot wounds from assaults and/or suicide attempts account for a high incidence of residual orofacial defects which can result in disfigurement or compromise of function. These injuries can often be assisted by this Centre.

Cancer

  •  In India, 20 per 100000 population are affected by oral cancer which accounts for about 30% of all types of cancer (1). Over 5 people in India die every hour every day because of oral cancer (2). The main objective in the management of malignant disease is cure, but there are important secondary goals to be considered as well. Specifically, an attempt is made to preserve form and function and retain an acceptable quality of life for the patient. This includes the use of dental osseointegrated implants and appropriate dental restorations. In the mouth, our focus is towards restoration and retention of teeth, and restoration of the ability to chew and swallow. Facial disfigurement can be overcome by restoration of the eyes, ears, noses, or other facial structures, by means of silicone prosthetics, occasionally retained by cranial implants.

Eye Prosthesis

ocular prosthesis

An Eye prosthesis also known as an ocular prosthesis is a substitute for the eye that has been lost due to birth defects, accidents or cancer surgery.

Frequently Asked Questions

If you have undergone any form of trauma or surgery that encompasses removal of the eye then we can replace the missing eye with an artificial prosthetic made out of acrylic.

Following healing of the eye socket a customised impression will be made of the defect. We will give you a transparent prosthesis (conformer) initially to allow you to get used to the idea of wearing the prosthesis. The conformer is then converted to the final eye prosthesis and this is stained with pigments to mimic your natural eye. A final clear layer is placed over this stained eye to protect it from the external environment. This layer will be highly polished to protect your defect area from any form of irritation.

The prosthesis is made out of a specialised acrylic material that is sensitive to UV radiation.

Fun
Facts

The earliest known prosthetic eye was found buried with a woman in Shahr-I Sokhta, Iran. It dated back to 2900-2800 BC and was made of bitumen paste covered with a thin layer of gold, engraved with a central iris from which lines radiated out like the rays of the sun.

These are some do’s and don’ts regarding after care of your prosthesis:

Do's:

  •   Clean the tissue surface of your prosthesis with a gentle soap or baby shampoo and a damp cloth.
  •   Wash the skin of the defect with mild soap.
  •   Initially you can remove the prosthesis at night but once you get comfortable with the prosthesis this frequency can reduce.
  •   Keep the prosthesis in an airtight container with some water in it when not in use. Keep this container in a dry and dark area away from sunlight.
  •   Remove the prosthesis when engaging in physical activities and contact sports (cricket, football, swimming etc).

Don’ts :

  •   Wear the prosthesis in the rain or during swimming
  •   Wash the skin of the defect with mild soap.
  •   Initially you can remove the prosthesis at night but once you get comfortable with the prosthesis this frequency can reduce.
  •   Keep the prosthesis in an airtight container with some water in it when not in use. Keep this container in a dry and dark area away from sunlight.
  •   Remove the prosthesis when engaging in physical activities and contact sports (cricket, football, swimming etc).

Ear Prosthesis

A Ear prosthesis also known as an auricular prosthesis is a substitute for the ear that has been lost due to birth defects, accidents or surgery.

Frequently Asked Questions

If you’re an individual who has lost either a part or whole of your ear then a prosthetic replacement would be ideal for you. This option prevents the need for further surgery and provides you with much better aesthetic results.

Following implant placement and healing in the region of the ear defect a specialised impression will be taken. A personalised wax mock-up will be fabricated for the defect for your approval. This wax model will be duplicated in a skin like material called silicone. The colour and texture of this silicone will be adjusted to suit your skin tone so that no difference is seen between the defect and the prosthesis.

Implant Bar Retained Prosthesis: An implant bar will be fabricated out of Cobalt Chromium Metal and will be fixed onto the implants. The silicone prosthesis will attach itself onto this bar by the means of elastic clips. This is the most basic means of retention for a ear prosthesis.
Implant Bar Prosthesis retained by Magnets: The implant bar will be fabricated and fixed onto the implants. A set of magnets will be attached to the bar as well as the silicone prosthesis. This makes placement of the prosthesis much easier and increases the lifetime of the prosthesis significantly.
Magnetic Bar Retained Prosthesis: The implant bar itself is made out of a special magnetic alloy (EFM alloy). This makes the entire assembly and prosthesis much more compact allowing a more life like and natural appearance. This is the best form of rehabilitation available.

The prosthesis is made out of a specialised silicone material that is sensitive to UV radiation and moisture.

Facts

The oldest known prosthetic was found in Cairo, Egypt. It was estimated that the wood and leather used was nearly 3,000 years old.

These are some do’s and don’ts regarding after care of your prosthesis:

Do's:

  •   Clean the tissue surface of your prosthesis with a gentle soap or baby shampoo and a damp cloth.
  •   Clean the surface and the skin surrounding the implants with a cotton bud and soap on a daily basis.
  •   Keep the prosthesis in an airtight container when not in use. Keep this container in a dry and dark area away from sunlight.
  •   Remove the prosthesis when engaging in physical activities and contact sports (cricket, football, swimming etc)

Don’ts:

  •   Wear the prosthesis in the rain or during swimming
  •   Wear the prosthesis in direct heavy sunlight. Wear a cap or hat to reduce the chances of damage to the prosthesis
  •   Rinse or clean the textured side of the prosthesis. This might cause the stain to come out and distort the prosthesis
  •   Try to clean the prosthesis with alcoholic solvents or heavy detergents

Mid Facial/Orbital Prosthesis

orbital prosthesis

A mid facial prosthesis also known as an orbital prosthesis is a substitute for the mid face and orbital region that has been lost due to birth defects, accidents or surgery.

Frequently Asked Questions

If you’re an individual who has lost either a part or whole of the orbital or mid face then a prosthetic replacement would be ideal for you. This option prevents the need for further surgery and provides you with much better aesthetic results.

Following healing in the region of the facial defect a specialised impression will be taken. A personalised wax mock-up with an eye if required will be fabricated for the defect for your approval. This wax model will be duplicated in a skin like material called silicone. The colour and texture of this silicone will be adjusted to suit your skin tone so that no difference is seen between the defect and the prosthesis.

Adhesive retained: The prosthesis in such cases will be retained by means of a special water - soluble adhesive. You will be shown how to apply and use this adhesive with your prosthesis.
Spectacle mounted: With larger defects or in cases where you already wear spectacles then we can attach your prosthesis to your existing frames. This form of mechanical retention is ideal if you have undergone radiation therapy which prevents the use of adhesives.
IF IMPLANTS ARE PLACED WITHIN THE DEFECT AREA – if you are suitable for implant placement and opt for the same then the retention and aesthetic outcomes of your prosthesis greatly improves. We will be happy to assist you in determining whether this option is indicated for you. If you have any queries please feel free to contact us regarding the same.
