Miniscrew-assisted single-tooth distraction osteogenesis to align an ankylosed infraoccluded maxillary central incisor: A case report.

J Orthod 2020 Dec 22;47(4):345-353. Epub 2020 Sep 22.

Department of Periodontics, Dental School, Islamic Azad University of Borujerd, Borujerd, Iran.

The ankylosis of permanent incisors is usually caused by trauma. In a growing patient, the ankylosed tooth fails to move along with the vertical growth of the remaining alveolar process, which results in an infraoccluded tooth, gingival margin disharmony and unaesthetic smile.This case report presents an 23-year-old female patient whose maxillary right central incisor (tooth number 11) had been traumatised eight years earlier.

Delayed Spontaneous Eruption of Severely Infraoccluded Primary Second Molar: Two Case Reports.

J Clin Pediatr Dent 2020 ;44(3):185-189

Infraocclusion occurs at an early age and becomes worse with age, causing increased damage in young children. Extraction of affected teeth is the preferred treatment modality for prevention of possible complications. It is rare for a primary molar to temporarily exhibit secondary failure of eruption, followed by regeneration of full eruptive capacity. Read More

Consequences of tooth luxation associated with complicated crown fracture: a case report.

Gen Dent 2020 May-Jun;68(3):57-61

The objective of this clinical case report is to describe the late treatment performed in a 10-year-old patient who suffered a complicated crown fracture associated with luxation of the maxillary left central incisor. The patient-s parents reported that the patient fell and was immediately taken to a hospital, where radiographs, splinting, and suturing were performed and an anti-inflammatory prescription was provided, but no treatment was given for the exposed pulp. The parents and patient sought treatment at a pediatric dentistry clinic 16 days post-trauma. Read More

Transcriptome analysis of ankylosed primary molars with infraocclusion.

Int J Oral Sci 2020 02 21;12(1). Epub 2020 Feb 21.

Florey Institute of Neuroscience, The University of Melbourne, Melbourne, Australia.

Primary molar ankylosis with infraocclusion can retard dental arch development and cause dental asymmetry. Despite its widespread prevalence, little is known about its molecular etiology and pathogenesis. To address this, RNA sequencing was used to generate transcriptomes of furcal bone from infraoccluded (n = 7) and non-infraoccluded (n = 9) primary second molars, all without succeeding biscuspids.

Interdisciplinary Approach to Treat Patients With Tooth Agenesis: A Case Report.

Clin Adv Periodontics 2019 03 5;9(1):34-46. Epub 2018 Jul 5.

Department of Periodontology, Boston University Goldman School of Dental Medicine.

Introduction: Tooth agenesis is a type of dental anomaly in which individuals are missing teeth due to developmental failure as a result of genetic or environmental factors. With approximately one fourth of the population missing ≥1 third molar, tooth agenesis is considered a common dental anomaly. However, the severity of tooth agenesis can range from a missing single tooth to multiple teeth. Read More

To extract or not to extract? Management of infraoccluded second primary molars without successors.

Br Dent J 2019 Jul;227(2):93-98

Orthodontic Department, University Dental Hospital, Cardiff, UK.

Infraocclusion is a term used to describe a tooth which has stopped its relative occlusal growth into the arch after the period of active eruption; as a result, the tooth becomes depressed below the occlusal plane. Although many aetiological mechanisms have been proposed, ankylosis is considered the primary cause of infraocclusion. Complex cases benefit from multidisciplinary management. Read More

Case Rep Dent 2019 11;2019:6916839. Epub 2019 Jun 11.

Universidad Europea de Valencia and the Department of Pediatric Dentistry, Universidad de Valencia, Spain.

Infraocclusion of deciduous molars is a quite common but challenging clinical situation that a paediatric dentist has to face in his everyday practice. This anomaly can lead to space loss, eruption disturbances of the permanent successor, and deformation of the occlusal plane. A case of a severely infraoccluded primary molar is presented. Read More

Long-term management of an ankylosed young permanent incisor replanted within 2 h of avulsion: A case report with a 10-year follow-up.

J Indian Soc Pedod Prev Dent 2019 Jan-Mar;37(1):99-106

Al Maher Medical Center, Dubai, UAE.

Tooth avulsion is a severe form of luxation injury that involves damage to both the pulp and the periodontal ligament. Avulsed teeth need to be replanted immediately in order to restore esthetics and function. Delayed replantation often results in ankylosis of the tooth which is a common sequela following avulsion injuries. Read More

Delayed tooth reimplantation with 4-year follow-up: the management of ankylosis during facial growth.

Gen Dent 2018 May-Jun;66(3):53-57

This case report describes the consequences of delayed (24 hours) reimplantation of an avulsed maxillary central incisor, findings over a 4-year follow-up period, and the management of ankylosis during facial growth. After a traumatic event, a 10-year-old boy was taken to a hospital emergency department due to injuries to his face, including avulsion of the maxillary left central incisor. Despite the short amount of time before arriving at the hospital (10 minutes) and use of the correct storage medium (milk), the tooth was not reimplanted, and the parents did not receive instructions to seek dental treatment.

Infraoccluded Upper Deciduous Second Molars Leading to Caries in the Permanent Dentition.

Dent Update 2015 Jun;42(5):485-7

Infraocclusion of primary teeth is a problem that can be recognized early by the general dental practitioner. Allowing affected teeth to deteriorate beyond a point where active intervention would be recommended can make treatment of the condition more complex or may lead to unexpected sequelae. The case described in this report of infraoccluded primary teeth, suffered pathology in adjacent teeth, leading to multiple extractions and fixed orthodontic treatment post surgery. Read More

A novel approach for building up infraoccluded ankylosed primary molars in cases of missing premolars: A case report.

Eur Arch Paediatr Dent 2015 Oct 5;16(5):425-9. Epub 2015 May 5.

Private Paediatric Dental Clinic, 2 Papadiamantopoulou Street, 11528, Athens, Greece.

Background: In cases of infraoccluded primary molars associated with agenesis of premolars, any treatment plan occasionally includes retention of the primary teeth for space preservation and future implant placement if needed. In these cases, building up the crowns to the occlusal line is necessary to prevent various clinical problems. The present case report describes in detail a novel but simple clinical approach for retention and building up of the crown of infraoccluded primary molars. Read More

Treatment strategies for infraoccluded dental implants.

J Prosthet Dent 2015 Mar 18;113(3):169-74. Epub 2014 Nov 18.

Professor, Department of Orthodontics, University of Basel, Basel, Switzerland.

Single-tooth implants in the maxillary anterior region have the highest risk of esthetic complications from infrapositioning due to continuing maxillary growth and the eruption of adjacent teeth. Although the placement of anterior single-tooth implants should normally be postponed, particularly girls and young women with a hyperdivergent growth pattern, if an infraposition of an implant is present, then thorough examination and strategic planning are required. According to the severity, the strategic treatment options are as follows: simple retention; adjustment or replacement of the implant restoration, possibly including adjacent teeth; surgical implant repositioning by segmental osteotomy combined with osseodistraction; or submergence or removal of the implant.

Coronectomy of two neighbouring ankylosed mandibular teeth--a case report.

Vojnosanit Pregl 2014 Aug;71(8):777-9

Introduction: Intentional partial odontectomy or coronectomy is primarily advocated in situations with intimate relationships between the roots of the tooth indicated for extraction and the inferior alveolar nerve (IAN). The aim of this report was to present a patient with two neighbouring infraoccluded teeth in the right mandible indicated for extraction prior to prosthetic rehabilitation, which were coronectomied as to prevent injuring of the IAN and causing iatrogenic fracture of the mandibular body.

Case Report: Coronectomy of both teeth was performed as recommended in the literature. Read More
