| Abstract|| |
Introduction: Various prostheses have been tried for intermediate restoration of esthetics, function, and speech in cleft patients but are usually associated with frequent breakages and oral hygiene problems. Hence, this modified arch holding appliance was designed to simultaneously replace the missing anterior teeth and stabilize the transverse changes in the maxillary arch, so as to restore the form and esthetics. Fabrication: Pickup impression with the molar bands was recorded; casts were poured in type III dental stone. Palatal arch holding appliance was fabricated and soldered to the molar bands on the first molars. Stainless steel wires were soldered vertically over labial aspect of the arch holding appliance forming plus (+)-shaped attachment, at positions of missing teeth. Acrylic teeth matching the patient's teeth were selected and adapted over this plus attachment and acrylized. Conclusion: This appliance may provide dual benefits to cleft lip and palate patients by restoration of esthetics while maintaining the transverse changes. It is easy to fabricate, durable, economical, and esthetically acceptable to the patient.

| Introduction|| |
Improvement of facial esthetics is one of the most important treatment objectives in management of cleft lip and palate (CLP) patients apart from restoration of proper function. Various modalities have been adopted in literature for prosthetic rehabilitation in CLP patients, which include removable/fixed prosthesis and dental implants. Early restoration of facial esthetics will enhance morale and self-esteem in these patients. With this objective in mind, a modified appliance for simultaneous arch holding (after maxillary expansion) and replacement of missing anterior teeth was designed, which has been mentioned in this article.

Pretreatment photographs [Figure 1]a, [Figure 1]b, [Figure 1]c shows missing 11, 12, and 13 along with maxillary arch after expansion and fixed orthodontic treatment in progress. Pickup impression with the molar bands was recorded using irreversible hydrocolloid impression material, and casts were poured in type III dental stone. Design of the appliance was marked [Figure 2]a. Palatal arch holding appliance was fabricated using 19-gauge stainless steel wire and soldered to the molar bands on the first molars. The horizontal extension of the wire in defect zone was extended up to the middle of buccolingual surface of the adjacent teeth (14 and 21). Seven-millimeter length (19 gauge) stainless steel wires were soldered vertically over labial aspect of this horizontal wire forming plus (+)-shaped attachment at planned positions of 11, 12, and 13 [Figure 2]b. Tooth shade and tooth shape were matched to the patient's natural teeth. Marking of plus (+) was transferred to the lingual surface of selected teeth at appropriate level. Grooves were made on these plus (+) markings to accommodate the wire same for additional retention [Figure 2]c. Teeth were placed in plus (+) shaped attachment, wax build up done to extend till the gingival contours and acrylised using heat cure acrylic. The gingival surfaces of the prosthesis were made in pink acrylic to match the gingival shade. Adjustments were done on the tissue side of the prosthesis to make itself cleansing [Figure 2]d. Posttreatment photographs showed marked improvement in smile esthetics of the patient [Figure 3]a, [Figure 3]b, [Figure 3]c.

| Discussion|| |
Arch expansion in CLP patients is usually done prior to alveolar grafting to reveal the entire cleft defect and to facilitate the eruption of teeth through the graft. Patients usually require long-term/permanent palatal retention to hold the transverse changes. Early restoration of esthetics by replacement of anterior teeth is usually difficult due to the palatal arch holding appliance and various other fixed orthodontic attachments. Various prostheses have been tried for intermediate restoration of esthetics, function, and speech in these patients, but these are usually associated with frequent breakages and oral hygiene problems., Hence, this appliance was designed to simultaneously replace the missing anterior teeth and stabilize the transverse changes in the maxillary arch. This appliance is easy to fabricate, durable, economical, and esthetically acceptable to the patient. In addition, it does not interfere with fixed orthodontic treatment.
| Conclusion|| |
This appliance may provide dual benefits to CLP patients by restoration of esthetics while maintaining the transverse changes. However, long-term clinical data are required to validate the results of this article.
