Abstract: A frictionally-retained detachable dental anchor device is provided for adjustably attaching a dental appliance with a tooth root or implant. The dental anchor device includes a cap secured in the dental appliance, an abutment attached with a tooth root or implant, and a compressible retention member with a first end in fixed attachment with the cap and a second end in snap engagement with the abutment via a frictionally-retained ball secured within a cavity of the abutment. The retention member is formed using a compressible material to allow the ball to compress and the retention member to flex while inserting the ball into the cavity. Additional friction-retained and fixed attachment configurations of the dental anchor device are provided, along with methods of securing a dental appliance in a subject's mouth by means of the friction-retained and fixed attachment dental anchor devices.

Abstract: A flexible arch model (FAM) is computed to capture and parameterize the variations of the multiple real dental arches in a training set to reconstruct missing teeth in a patient's dental anatomy. Building the FAM includes acquiring multiple sets of digitized dental arches with a pair of maxillary (upper) and mandibular (lower) jaws in the right relative position and gathering a pre-defined set of landmark points on the occlusal surface of each arch all in the same order and same corresponding positions across multiple samples. The gathered vectors of landmark points are used to perform statistical modeling (e.g. Principal Component Analysis) to create a linear subspace of the feature points with the basis of principal components (when PCA is used) found during the procedure. An arbitrary set of landmark points on a pair of upper and lower arches can be reconstructed by a linear combination of the principal components within a reasonable range of variations captured from the training samples.

The fixture comprises a top, a bottom, a peripheral surface connected between the top and the bottom, and a joining portion formed on the peripheral surface. The abutment is set on the top of the fixture. The connecting structure is set between the fixture and the abutment. The wings are pivotally connected with two opposite sides of the connecting structure. Or, one of the wings is pivotally connected with the connecting structure, and the other wing is fixed with the connecting structure. The wing or the wings may be adjusted to fit the surface of the cortical bone. Dental posts are allowed to penetrate the alveolar bone entirely to secure the fixture.
