Using Pruning-Based YOLOv3 Deep Learning Algorithm for Accurate Detection of Sheep Face.

Accurate identification of sheep is important for achieving precise animal management and welfare farming in large farms. In this study, a sheep face detection method based on YOLOv3 model pruning is proposed, abbreviated as YOLOv3-P in the text. The method is used to identify sheep in pastures, reduce stress and achieve welfare farming.

[Clinical study of healing abutment on sealing socket and preservation of the gingival natural profile in single-tooth immediate implantation].

Objective: To investigate the clinical results of use of healing abutment for sealing socket and preserving the gingival natural profile in single-tooth immediate implantation.

Methods: The osteotomy site was prepared with pilot drill directed by the periodontal probe on palatal wall of the socket,and 31 single-implant were placed into fresh sockets with flapless surgery and filled with Bio-oss. Healing abutments were simultaneously fitted on implants and ceramic crowns fabricated three months post-operation.
