Anterior crossbite is the term used to describe an abnormal labiolingual relationship between one or more maxillary and mandibular incisor teeth. Different techniques have been used to correct anterior crossbite. This paper describes the use of a simple fixed appliance for the management of anterior crossbite. The procedure used was a simple and effective method for treating anterior dental crossbite without extraction

Keywords : Anterior; malocclusions, fixed appliance, non extraction


Anterior crossbite is defined as a malocclusion resulting from the lingual positioning of the maxillary anterior teeth in relationship to the mandibular anterior teeth.1 Dental crossbite involves localized tipping of a tooth or teeth and does not involve basal bone.2 Anterior dental crossbite requires early and immediate treatment.

A variety of factors have been reported to cause anterior dental crossbite, including a lingual eruption path of the maxillary anterior incisors; trauma to the primary incisor resulting in lingual displacement of the permanent tooth germ; supernumerary anterior teeth; an over-retained necrotic or pulpless deciduous tooth or root; odontomas; crowding in the incisor region; inadequate arch length; and a habit of biting the upper lip.3–9

There are various treatment modalities used for the correction of anterior dental cross bite. These include tongue blade therapy, reverse stainless steel crowns, removable Hawley retainer with anterior Z-springs and bonded resin composite slopes10,Bruckl appliance and Clear Aligner11

This report presents a method of treating a case of anterior crossbite of dental origin.

Case presentation and examination

A 27 year old male patient, presented with Class II malocclusion and anterior crossbite of upper and lower all incisors. His chief complaint was unaesthetic facial appearance, and a missing upper central incisor. Patient had visited a dentist before of the same where he was advised to undergo orthodontic treatment but he was not willing to undergo orthodontic treatment and wanted some immediate short term treatment.[fig1]

The following treatment options were discussed with the patient:
  1. Extraction of tooth 11root piece , orthodontic correction of upper and lower anteriors, placement of an implant and crown for tooth11.
  2. Extraction of tooth11 root piece, intentional root canal treatment for 21 and giving an metal free ceramic bridge(fixed partial denture) from 13 to 23 and without extraction of the lingually placed32 and 42 ,metal free ceramic bridge(fixed partial denture) with a pontic in region of 32 .

The patient reported to the clinic after 2days and was willing to undergo the 2nd option given.


The following procedures were executed at subsequent appointments based on the clinical findings. The first appointment, non traumatic extraction of 11 root piece and badly carious 22 was done and the extraction site was allowed to heal for one week. In the next appointment intentional root canal treatment was done with 21 on the day of suture removal.

The 2nd appointment was scheduled a week later where in the abutment teeth 12,21,23 and 31 ,41 were prepared. The incisal margin of 21 were over cut to correct the over jet and the lower lateral incisors were not extracted and were kept as it is. Final impressions were made with addition elastomer impression material.

The dental technician was given the illustration of the bridge to be made based on the clinical needs. The frame work wax up was done on the cast an additional pontic was asked to attached in 32 region as the space was wide enough to accommodate an additional teeth (fig2). after the approval of wax up, a metal frame work was made and try in was done in the patient's mouth to check the fit of margins as well as the over jet. In the final appointment the fixed partial denture was cemented in with glass ionomer cement after occlusal correction(fig 3).

Orthodontic treatment to correct the position of teeth would have been the best option but because of its duration and cost. the patient refused this option .

The main advantages of a fixed denture included the possibility of correcting the anterior crossbite more quickly and less expensively than would have been the case with orthodontic therapy11–13

The treatment done in this patient has been supported by authors, such as Ning,14 where in his 27 cases of anterior crossbite that were corrected with fixed partial denture .there was, no clinical, functional or esthetic problems identified during follow-up after 3 years.

When faced with various esthetic challenges. the optical properties of available ceramic systems enable the clinician to make appropriate choices


This method represents a safe, quick, easy and esthetically acceptable alternative for the correction of anterior dental crossbite. The procedure is low-cost, involves no discomfort, and it can be completed in only a few visits to the clinic. The success of treatment with a fixed partial denture depends on the diagnosis, treatment planning by the dentist and the patient’s concerns. Appropriate evaluation of the patient, prosthetic design and tooth preparation, as well as good oral hygiene, are all required for success.
