Background:
Implant aesthetics of anterior regions requires balanced tooth dimensions and harmoniously scalloped and convex soft tissue contours.
In cases of mild horizontal defects, the adequate alveolar contour can be addressed exclusively using soft tissue procedures without the need for bone augmentation.
Minimally invasive correction of the soft tissue deformity using the roll flap technique suggests that it produces similar results to those of higher morbidity grafting techniques. 

	Aim:
The aim of the present work is to report the long-term follow-up of a series of cases of tooth replacement in the anterior region with mild resorption of the buccal plate in which the alveolar contour was rebuilt using the roll-flap technique.  

	Material and Methods:
	We present 3 cases with 4 to 6 years of follow-up.
	Contour augmentation of the soft tissue on the buccal aspect of the restoration, particularly in what concerns the height and thickness of the keratinized gingival epithelium was restored using a flapless technique combined with a modification of Abram’s roll flap technique. The technique consists of the de-epithelization of the gingiva over the alveolar crest followed by a pediculate incision on the alveolar ridge towards the buccal surface, followed by partial thickness pediculate flap reflection towards the buccal surface with partial thickness envelope preparation on the base of the pedicle, enrolment and stabilization with suture. The technique proceeds with the implant placement and immediate function with provisional rehabilitation or with a healing abutment. Any gap between the healing abutment and the limit of the incision heals by secondary wound closure. 

	Results:
	After 4 to 6 years there is a stabilization in the volume of soft tissue obtained with the roll technique. 

	Conclusion and Clinical implications:
Providing higher thickness of soft tissue over the buccal side of the alveolar ridge allows the achievement of an harmonious convex contour with the adjacent teeth and guarantees greater possibility of adequate biological width, which might influence the long term success of the restoration by providing marginal biological sealing.
 	The described procedure is technically simple, not time consuming and has low post-surgery morbidity.
