a. Initial clinical situation of the patient with advanced periodontal compromise and severe mobility of the teeth. Pre-treatment radiological evaluation was carried out to analyze bone volume and to plan implant placement.

b. Digital planning of the screw channel orientation, comparing straight and angulated channels. Angulated screw channels were used to correct the implant angulation and to relocate the screw access away from the esthetic zone.

c. Clinical situation after the surgical phase of the treatment, with implant placement and a provisional prosthesis in place.

d. Estructura protésica definitiva fresada mediante CAD/CAM con orientación precisa de los canales de tornillo angulados.


Final esthetic result after placement of the definitive prosthesis in a patient with a high smile line, without visible compromise from the screw access channels. The clinical case was originally published in the scientific journal Dentale Implantologie, Vol. 23, No. 2 (2019).

a. Fabrication and adjustment of the model where three BHS30 Titanium Bases are mounted on straight Multi-Unit abutments, which are fixed by means of their corresponding BHS30 MU screws.

b. Scanning of the model with attachments and scanning of interfaces and screws in a second phase.

c. BHS30 solution in multiple esthetic anterior sector prosthesis. Both files (model + attachments) are retrieved and the direction of the transocclusal canals is corrected to optimize their emergence points according to the anatomy of the prosthesis.

d. The framework is machined on a Zirconia (Zr) disk according to the requirements of the design phase and cemented on BHS30 Ti interfaces, facilitating a good fit test result on the model.

e. Final aesthetics of the finished work before placement in the mouth.

a. Unitary prosthesis for an upper molar (26), with very lingualized emergence. The BHS30 solution corrects the transocclusal canal to improve the functionality of the restoration.

b. Details of the new direction of the canal after placement of the angled BHS30 castable and once the finished piece is attached to the analog, where we can see the increase in the thickness of the palatal wall and the strength of the piece.

c. Check the fit of the part on the model, securing it to the analog with the help of the BHS30 Protractor. The access orifice to the transocclusal canal is observed in its new position. This occlusal view shows the easy visual identification of the unique spherical head of the BHS30 screw inside the canal. Final aesthetics of the restoration.

a. Emergency correction of the Multi-Unit abutment using a BHS30 MU M1.4 screw, which avoids invasion of the chewing cusp of the lateral incisor (32).

b. Comparison of the optimization of the vertical dimension of the access hole for the fastening screw after completion of the work.

c. Visual differentiation of BHS fasteners, which ensures the use of the right tool, protecting the integrity of the bolt head. Final aspect on the vestibular side of the work, with esthetic finish.

Patient with a fixed anterior prosthesis cemented on natural teeth, whose recent fracture causes mobility and instability of the prosthesis. He comes in search of a solution to improve the esthetics of his smile. Initially, a treatment based on the removal of the prosthesis and the damaged teeth, and the placement of four implants in positions 22, 21, 12 and 14, correcting their emergence profile by means of conical transepithelial abutments angled at 17 degrees, was chosen. Subsequently, the resorption of the gingiva uncovered the shoulder of one of the abutments and it was decided to replace them with straight Multiunits, saving the vestibular emergence by means of BHS30 sockets at 20 degrees and BHS30 screws.

a. Initial scenario of the case after the diagnostic visit, where the deterioration of the anterior cemented prosthesis is observed.

b. After designing the treatment plan, the laboratory makes a temporary acrylic structure for immediate loading to be screwed on four implants, whose vestibular emergence profile is corrected by placing Multi-Unit abutments angled at 17º.

c. After removal of the damaged structure and natural teeth, implants are inserted and immediate loading is performed, with good esthetic results.

d. After 8 months, due to the resorption of the gingival tissue, the shoulder of the transepithelial in position 14 is exposed.

e. The angled abutments are replaced by straight Multi-Unit abutments, with a 1 mm shoulder, to reduce the profile of the prosthesis.

f. Taking impressions with open tray for the reconstruction of the laboratory model. The printing pillars show emergencies we face.

g. Once the straight Multi-Units have been incorporated into the model, the prosthesis is fabricated by casting on 20º BHS30 angled castable cylinders, which will be fixed to the Multi-Unit abutments with compatible BHS30 screws.

h. After a successful bisque test, the ceramic is glazed and the prosthesis is screwed into the mouth.
