Retention and stability are the main objectives in a complete denture fabrication. The weight of a maxillary complete denture is one of the factors that affects its retention and stability. Excessive interarch distance between the maxillary and mandibular edentulous arches increases the height and weight of the prosthesis, thus compromising the retention. Long lip length further compromises the situation. This article describes a case report of prosthetic rehabilitation of a patient with bilateral gross asymmetry due to unilateral Bell's palsy and increased prosthetic space by fabricating a light-weighted hollow denture to improve the esthetics and function.

| Introduction|| |
Bell's palsy is a unilateral paralysis of the facial nerve that affects the voluntary movement of the facial muscles compromising the esthetics and function. In a prosthodontic perspective, the difficulties encountered are cheek biting, uncontrolled salivary flow, and expressionless mask-like appearance., All these clinical features interfere with all the prosthodontic steps, thus affecting the denture retention and stability. The long upper lip and excessive inter-ridge space further add to these clinical problems by making the denture heavy. Decreasing the weight of the maxillary obturator by fabricating a hollow denture base to restore a large maxillofacial defect has been proven to be beneficial., Therefore, the denture base of a maxillary removable prosthesis can be made hollow to reduce its weight, thus enhancing the retention and stability.
Various techniques such as utilizing solid three-dimensional spacer, including dental stone,,,,,, silicone putty,,, modeling clay,, or cellophane-wrapped asbestos, caramel spacer, and clear template of trial denture to create gelatin cavity were implemented to replace the acrylic resin with a hollow cavity in the denture base. This case report describes a technique of using addition silicone putty to create hollow space in the denture base to lessen the weight.
| Case Report|| |
A 72 year old male patient (consent obtained) reported to the department of prosthodontics with a chief complaint of the replacement of missing teeth and bilateral asymmetry of the face. History revealed that the patient abruptly developed paralysis of the left side of the face 1 year ago and had been edentulous since. On extraoral examination, the clinical features observed were leptoprosopic face with bilateral gross asymmetry, drooping of the left angle of the mouth, long upper lip, and significant decrease in the muscle tonicity [Figure 1]. Intraoral examination revealed well-formed maxillary and mandibular edentulous residual alveolar ridges. Considering all the available treatment options, it was decided to fabricate a maxillary hollow complete denture and mandibular conventional complete denture.
- Conventional technique of making preliminary and final impressions was implemented
- During the clinical step of maxilla-mandibular relations, to enhance the esthetics with the long upper lip, the occlusal rims were adjusted which revealed the vertical dimension at rest and vertical dimension at occlusion to be more than normal
- Monoplane teeth were selected as the patient's neuromuscular control was poor due to the facial asymmetry
- Teeth arrangement was done in balanced occlusion. Then try-in done separately for anterior and posterior teeth
- Flasking and dewaxing were done according to the conventional procedure
- After dewaxing, addition silicone putty was manipulated and adapted into space available in the flask. An index was cutout from the adapted putty [Figure 2], and trial closure was done
- Heat-cured poly-methyl-methacrylate resin was manipulated and divided into two halves. The first half was directly adapted onto the dewaxed mold [Figure 3]
- Then the putty index was accurately positioned, over which the remaining heat cure acrylic resin was packed and cured at 70°C for 7–8 h
- Access holes were made in the retrieved denture distal to second molars and palatal to anterior teeth [Figure 4] to remove the putty index
- After ensuring the complete removal of putty, the access holes were closed with autopolymerizing resin, and the denture was trimmed, finished, and polished
- The denture was checked for seal by immersing in water to observe any air bubbles [Figure 5] and then delivered to the patient [Figure 6].
Merits of this technique
- The putty index provides uniform thickness of acrylic resin in the denture
- Adequate seal between two portions of acrylic resin is obtained without any leakage
Demerits of this technique:
- Retrieval of putty from the denture was technique sensitive, time-consuming, and tedious which required additional access holes palatal to the anterior teeth
- This weakens the denture making it less resistant to fractures.
| Discussion|| |
Prosthodontic rehabilitation of completely edentulous maxillary and mandibular arches in patients with Bell's palsy who lack voluntary muscle control is challenging to the dentist as they pose clinical difficulties. Contemplating the economic constraints, systemic conditions, and reluctance to undergo long and extensive surgical procedures, in geriatric patients, conventional complete dentures were considered to be the best way to rehabilitate. To overshadow the esthetic challenges of facial palsy, as a palliative therapy, dentures were modified with padding for buccal flanges, spring-loaded acrylic flanges, and magnet retained cheek plumpers to improve cheek support.
Increased weight of the denture, owing to excessive interarch distance and long upper lip, can be dampened by creating a hollow space in the denture base to enhance the retention and stability for which numerous materials and techniques were followed. This method utilizes addition silicone putty spacer as it is dimensionally stable, easy to contour, and is considered the most desirable material to fabricate light-weighted dentures.
The fabricated hollow denture:
- Restored the function of mastication
- Enhanced the comfort due to its lightweight and
- Improved the esthetics by providing additional support to the cheek.
