Two treatment alternatives were available: implant restoration of the first molar with poor prognosis or mesialization of the second and third molars to substitute the first and second molars. The patient finally chose the second treatment option. Ridge augmentation with bone grafting was performed to deal with alveolar atrophy at the first-molar extraction site. Molar protraction was accomplished with a novel protraction loop appliance (Albert loop) that was anchored onto an interradicular mini-implant. At the end of the treatment, excellent buccal interdigitations and good root parallelism were achieved.

Restricted to the English language and publication date up to 23/3/2024, the searches in published literature covered the following databases: MEDLINE, PubMed, EMBASE, Tripe, Web of Science, Scopus and PubMed Central. However, unpublished literature was searched at ClinicalTrials.gov, National Research Register, and ProQuest Dissertations and Theses. Lists of all eligible studies were checked for further scrutiny.

All the reviewed articles studied the pain during debonding events and included 886 patients aged between 12–65. They used different scales such as VAS, NRS, Wong–Baker faces, and others scales. Two studies have shown that the lift-off plier causes less pain than other pliers when comparing different types of dental instruments. However, when comparing different adjunctive techniques, two studies have found that using a wafer causes less pain, while two studies have reported no significant difference between methods and one study has found that using finger pressure causes less pain. In addition, three separate studies have found that utilizing an ultrasonic device, as well as a thermal device and laser radiation, can lead to lower pain scores.
