One Stage Implant Problems

Dr. Cutnei from Brazil asks us:
At our practice when we are working with a one stage dental implant
system, we notice some limitations in the esthetic zone.

Specifically, when working with ITI Straumann dental implants in anterior region of mandible, where we all know we have a very nonkeratinized and thin mucoso in the lingual section of anterior mandible, we are always confronted with a thin and tearable and non attached mucosa in the lingual aspect of dental implant. This situation could predispose the patient for bone loss in the area. What should I do? Should I move to a 2 Stage implant process in the anterior of mandible and make a bucal flap instead of crestal flap? Thanks for any help.
