A Simplified approach for fabrication of custom tray for Facial prosthesis

Maxillofacial defects can be either congenital or acquired defect. Defect is not acceptable for the patient nor to the family of the patient in view of esthetic appearance and function. It hampers patient’s life and socially unacceptable [1]. Defects can be due to squamous cell carcinoma or basal cell carcinoma [2]. Malignancies of the nasal septum are considered rare, and accounts for 9% of all cancers of nasal cavity [3]. Squamous cell carcinoma comprises about 66% of such lesions [4]. In the past several techniques have been de ined for taking impression for facial defects using stock trays or not using stock trays [5-7]. Various materials have also been given in past with which impression can be made [8]. Kusum, et al. de ined an innovative technique of taking facial impression by fabricating a stock tray of acrylic and with hinge attachment for accurate impression taking [9].


Introduction
Maxillofacial defects can be either congenital or acquired defect. Defect is not acceptable for the patient nor to the family of the patient in view of esthetic appearance and function. It hampers patient's life and socially unacceptable [1]. Defects can be due to squamous cell carcinoma or basal cell carcinoma [2]. Malignancies of the nasal septum are considered rare, and accounts for 9% of all cancers of nasal cavity [3]. Squamous cell carcinoma comprises about 66% of such lesions [4]. In the past several techniques have been de ined for taking impression for facial defects using stock trays or not using stock trays [5][6][7]. Various materials have also been given in past with which impression can be made [8]. Kusum, et al. de ined an innovative technique of taking facial impression by fabricating a stock tray of acrylic and with hinge attachment for accurate impression taking [9].
Most of the facial defect's impression can be obtained by using the present described technique. The stock tray, fabricated by this method can be used to take the inal impression of the facial defect by using any suitable impression materials. This technique is simpli ied as well as cost effective.
The quality of life reduced due to such maxillofacial defect. Prosthetic management after trauma or surgery has been well documented. The purpose of this technical note was to describe a custom sculpted de initive facial custom tray for making facial impression. 9. This custom tray can now be retrieved from model as shown, and small holes with straight issure bur can be made (Figure 3). 10. This tray can also be used in other patient with facial defects.

Abstract
Maxillofacial defects are very common and can be due to congenital defect, trauma, infections and neoplasms of facial region. These defects can be restored using diff erent materials and retention methods to give a life like appearance. Rehabilitation of facial defect is a very challenging task. Every good prosthesis needs a skillful hand and it all starts with making a good impression of that defect and to proceed with the same. The aim of present paper was to present a simplifi ed approach for the fabrication of custom tray to take facial impression of the patient with maxillofacial defect. https://doi.org/10.29328/journal.jcad.1001021

Discussion
Facial defects result in esthetic, functional and psychosocial dif iculties [10]. Surgical reconstruction techniques, prosthetic rehabilitation or a combination of both the methods to restore these facial dis igurements may improve the level of function and self-con idence for patients [11]. The site, size, and etiology of the defect, patient's age, general medical condition and desire are used to determine the methods of reconstruction [12,13].
Prosthetic rehabilitation can be preferred due to probability of recurrence, complexity of the surgical reconstruction procedure, radiation therapy, and esthetic importance.

Conclusion
The approach for fabricating the custom tray, described in this article is simple and easy to use and can be used in any kind of extraoral defect in whom impression making is required. This custom tray can easily be used with any impression materials like irreversible hydrocolloid or elastomeric impression.
