The epithelial sulcus is kept short thanks to the coronal migration of the collagen fibres led by the convergent neck.

The convergent morphology of the neck of the Prama implant allows an excellent adhesion of the collagen fibres with a resulting coronal migration of the connective tissue.
In this rearrangement of the peri-implant soft tissues the morphology of the prosthesis also plays a key role. The prosthetic restoration is indeed fabricated according to the principles of the B.O.P.T. technique: it presents a characteristic emergence profile around which soft tissues grow and adjust over time.

The benefits produced by the convergence of the neck, associated with those of the B.O.P.T. protocol, allow an effective seal at the prosthetic sulcus: this results in a short and horizontal probing of the sulcus, that leads to a high aesthetic value with stable and functional tissues.

Let’s expand on the subject with the case of Dr. Guillermo Cabanes Gumbau up next.

Clinical case: prosthetic seal with the B.O.P.T. technique from natural teeth to implants.

The case shows the rehabilitation of a patient treated at the same time with B.O.P.T. technique on the natural tooth and with implant surgery.

The rehabilitation includes a 6 elements cemented bridge on 3 natural posts prepared using the B.O.P.T. technique and an adjacent element rehabilitated with cemented crown on Prama implant.

Two weeks after the delivery of the bridge and of the crown the result is similar: during clinical observation and probing it is possible to appreciate the quality of the biological seal generated by the migration of the soft tissues toward coronal level, both around the natural posts and around the post of the Prama implant.

Initial situation: the patient presented with single edentulism of 2.4 and advanced periodontal disease of the 1.2, 2.1 and 2.2 teeth that cannot be considered a reliable prosthetic posts to support a bridge, not even for a short time.

2.4 is replaced by a Prama implant 3.80 ∅ height 13.00 mm, while the teeth of the anterior sector are rehabilitated with a bridge fabricated according to the B.O.P.T. technique. Element 2.3 also undergoes a graft of connective tissue.

After the provisional phase the periodontal situation is completely resolved. A B.O.P.T final crown is cemented on the implant in position 2.4 , with no need of a temporary crown

Follow up two weeks after the cementation of a metal-ceramic bridge on the elements from 1.3 to 2.3 and of a metal-ceramic implant-supported crown in position 2.4.

The quality of the horizontal biological seal generated by the thickness and by the adaptation of the soft tissues at coronal level, both around the natural posts, and around the posts of the Prama implant can be appreciated during clinical observation and probing. The B.O.P.T. philosophy and approach produces the same results in both cases.
