Collision Tumour Comprising Desmoplastic Ameloblastoma and Squamous Odontogenic Tumour in the Anterior Maxilla: A Case Report.

Collision tumours, characterized by the simultaneous occurrence of two distinct neoplasms within the same anatomical site, are exceedingly rare in oral pathology. This case report presents an uncommon collision tumour involving desmoplastic ameloblastoma and squamous odontogenic tumour in the anterior maxilla of a 52-year-old male from the Indian population. Desmoplastic ameloblastoma is a variant of ameloblastoma known for its unique histopathological features, while squamous odontogenic tumour is a benign epithelial odontogenic tumour with distinctive clinical behaviour.

Patient-Specific Implants (PSI) in Maxillary Hypoplasia Secondary to Cleft Lip and Palate Deformity.

Maxillary hypoplasia is often evident in cleft patients due to impaired growth and dense scarring from previous cleft surgeries. For these patients, treatment scenario has taken many turns over ages, evolved from orthognathic correction to distraction osteogenesis, with mixed prognosis and outcome depending on severity of the case and other several factors. We are reporting a case of 24-year-old female with maxillary hypoplasia secondary to bilateral cleft lip and palate with hypoplastic prolabium, who has been treated with two patient-specific implants in bilateral maxillary region for facial profile enhancement.
