Abstract: An orthodontic expansion device includes a pair of opposed lateral portions, each of which includes a molar band shaped to be positioned on molars or other teeth of a patient. A palate frame extends obliquely from the molar band. The device further includes a tensioned tensioning assembly positioned between the pair of opposed lateral portions that applies an outward pressure on the palate of the patient. The tensioning assembly is at least partially detachable for adjusting the tension of the device. As the palate expands, and the tension in the device relaxes, the tensioning assembly can readily be detached, retensioned, and reattached.

Abstract: A kit and assembly for removing embedded dental roots including the provision of multiple drill sleeves of varying diameter and configurations which drill into the bone around the embedded root in order to progressively shape a retrieval profile surrounding the embedded root to be removed. According to a non-limiting preferred embodiment, a series of three drill sleeves are employed for shaping the profile for subsequent insertion of a uniquely configured retrieval forceps for gripping the embedded root surfaces revealed by the drill rings for easy removal. In this fashion, removal of the embedded root is facilitated without inflicting undue damage to the surrounding bone. As further explained, the kit can be reconfigured as required for removing multiple embedded molar root tips of varying configurations.

Abstract: An orthodontic device for cranial adaptations envisaged to be allocated between a patient's two dental arches. The device includes a lower vestibular shield (3) envisaged to engage externally with the dental arch not concerned by the treatment, and a front shield (4) designed to rest against the incisors. A palatal shield (40) is provided to strengthen the pressure which the patient applies while contracting the musculature and to allow the maxillae to expand, thereby widening the upper arch. Additionally, the device features an upper lingual shield (5) equipped with a lingual ramp (50) envisaged to ensure the tongue remains in a specific well-defined area, at the incisor teeth, and delimited on one side by the device and on the other by lingual pins (11) present in an aligner (10) which the patient must wear since the device works in conjunction with the aligner, aided by a median ridge (9).

Abstract: A self-cleaning dental mirror tool. The dental mirror tool includes a handle portion, a neck portion, a power pack, and a head portion. The handle portion holds the power pack. The power pack is self-contained within a housing. This power pack comprises a motor, a control switch, and one or more batteries. The power pack is removable from the handle portion. An adaptor is affixed to the end of the drive shaft of the motor. The adaptor engages a pinion having a circular bevel gear. The circular bevel gear engages an annular gearing ring on a rotor assembly having a rotor shaft and a disc to which a mirror is affixed. The mirror may be in the form of a detachable sticker with a reflective surface. In use, the mirror rotates at high speed. This high-speed rotation expels water and debris from the surface of the mirror.

The sagittal adjustment portion is configured to adjust a maxillomandibular position relationship while at least to partially offset deformation of the shell-like body caused by occlusion, and the sagittal adjustment portion is at least partially connected to the lingual side in the anterior region of the shell-like body. The sagittal adjustment portion has a geometric structure configured to stabilize a maxillomandibular occlusion relationship and reduce a deformation of the shell-like body caused by occlusion while to adjust positions of teeth in a mandibular anterior region relative to a maxilla upward to target occlusion positions in a sagittal direction.

Abstract: A dental coil spring extension device capable of extending a pitch of the dental coil spring is disclosed. The dental coil spring extension device includes a first grip part, a second grip part, and an extension part. The first grip part grips one coil of a coil spring.

The movement velocity is determined independently for each tooth, and the movement velocity for the at least one tooth is determined independently for each direction.

Abstract: The disclosed computer-implemented method for selecting locations of mandibular relocation features (MRFs) on oral appliances may include determining candidate locations for placing an MRF on a first oral appliance for a first stage of mandibular relocation (MR) treatment and determining candidate locations for placing an MRF on a second oral appliance for a second stage. The method may include selecting from the candidate locations for the first stage and the second stage based on decreasing a distance between the selected pair of candidate locations. The method may further include processing multiple MRFs in parallel. The method may also include increasing a number of initial candidate locations. Locations for intermediate stages may be selected based on interpolating between the first and second stages or based on decreasing a distance between the selected pair if the interpolation fails. The intermediate stages may be processed using a binary search or a linear search.
