“…It has been reported that FPM extraction usually increases the overall fixed appliance treatment time by 6-9 months compared to an equivalent case in which four premolars are extracted. 3 Temporary anchorage devices such as mini-implants can be utilized to assist in the closure of large lower FPM extraction spaces (Fig 13). These bone anchorage devices can also prevent undesirable anterior segment retraction during space closure.…”

The first permanent molar (FPM) is commonly subject to significant compromise which may arise due to caries or endodontic complication, or from developmental anomalies such as hypoplasia. Compromised teeth with questionable prognosis may result in short and long-term clinical dilemmas. This review article highlights the factors that require careful consideration when a compromised FPM is detected and the importance of timely FPM extraction. Several clinical cases are described in detail to discuss possible treatment options from the orthodontic perspective.

“…Fixed appliances are invariably needed at this stage to align the teeth and achieve space closure with parallel roots. 20 The effects are more of a problem in the lower arch, where the second molar tips mesially and rolls lingually forming a very poor contact with the second premolar or may leave excess space. Little spontaneous relief of anterior crowding is seen.…”

Orthodontics. Part 8: Extractions in orthodontics

Extractions in orthodontics remains a relatively controversial area. It is not possible to treat all malocclusions without taking out any teeth. The factors which affect the decision to extract include the patient's medical history, the attitude to treatment, oral hygiene, caries rates and the quality of teeth. Extractions of specific teeth are required in the various presentations of malocclusion. In some situations careful timing of extractions may result in spontaneous correction of the malocclusion.

“…[3][4][5][6] Extraction of FPMs with poor prognosis has been advised in the orthodontic literature. 7,8 However, there are many fac tors that should be considered when treatment planning for patients with grossly carious FPMs. 9 The ideal time for the loss of a FPM is with the commencement of calcifi cation of the bifurcation of the second permanent molars, 10 which usually occurs at a chronological age of eight to ten years.…”

Extraction of first permanent molar teeth: results from three dental hospitals

• Caries is the main reason for the extraction of first permanent molars in children.• Children who are attending dental hospitals for extraction of first permanent molars tend to be older than the optimal age for achieving space closure.• There is a need for guidelines advising primary care dentists when to refer children for the extraction of fi rst permanent molars.• This study highlights the need for extensive prevention programmes targeted at those children with high caries risk.Extraction of first permanent molar teeth: results from three dental hospitals The main reason for extraction was caries with poor prognosis (70%); molar incisor hypomineralisation was the reason for extraction in 11% of cases. General anaesthesia was the main anaesthetic method used in 77%, 55%, and 47% of cases in Manchester, Liverpool and Sheffi eld respectively. Sixty-eight percent of cases had not received previous treatment for the FPMs and 5% had fissure sealants detected. Forty percent of children had had previous extractions. Conclusion The children who are attending the hospitals for extrac tion of FPMs tend to be older than the recommended age for achieving spontaneous space closure. This study highlights the need for extensive prevention programs targeted at those children with high caries risk.
