Aims: Extended orthodontic treatment leads to a number of negative outcomes, including a higher chance of dental cavities, gingival recession, open gingival embrasure gaps, and root resorption. It has been stated that micro osteoperforations (MOPs) use the biology of the body to speed up tooth movement. Our objective was to investigate how MOPs with micro implants affected the tooth movement rate.

Background: In clear aligner therapy, tooth movement can be designed individually by computer software. However, the deformation of the aligner created by the virtual movement of one tooth may affect the actual movement of other teeth. This study aimed to evaluate the impact of the amount of canine movement on the responses of incisors and posterior teeth during maxillary anterior en-masse retraction with clear aligner.

Background: Hydrostatic pressure in the periodontal ligament (PDL) plays a critical role in orthodontic treatment, influencing tooth movement and remodeling of periodontal tissue. The relationship between alveolar cortical bone density and the risk of root resorption due to excessive stress in the PDL has not been clearly defined.
Objective: This study aimed to analyze hydrostatic pressure in the periodontal ligament of the tooth roots during en-masse retraction of the maxillary incisors using temporary skeletal anchorage devices (TISADs) after the first premolar extractions, as well as during full arch retraction.

Objective: To investigate the effect of deferred timing of therapeutic extraction on the rate of space closure during en masse anterior retraction.
Methods: Twenty-six patients (aged 16-24 years) with bimaxillary protrusion, crowding <3 mm, requiring bilateral extraction of four first premolars were recruited. Permuted block randomization was done.

Class I bimaxillary protrusion is characterized by proclined incisors, a convex facial profile, procumbent lips, and increased lip strain. Treatment includes the extraction of premolars and the mesial movement of the proclined anterior teeth in the extraction spaces to correct the inclination. This case report describes the treatment of an 18-year-old male patient who presented with class I bimaxillary protrusion and procumbent lips.
