Unless the barrier is exposed, it can remain in place for several months to years but it require a subsequent surgical procedure to remove them. Bone augmentation and simultaneous implant surgery procedures allow clinicians to reconstruct alveolarbonedeficiencies,preservealveolardimen- sions,andreplacemissingteethwithdentalimplants in a prosthetically driven position with natural ap- pearance and function. The 2-year clinical results obtained in this case demonstrate CPS alloplast with GBR along with simultaneous implant place- ment to be a predictable and successful procedure to augment bone at sites exhibiting insufficient bonevolumeforimplantplacementunderstandard conditions and proved to be a successful strategy for anterior aesthetic rehabilitation. Conclusion Placing dental implants in the maxillary anterior regionrequirespreciseplanning,surgery,andpros- thetic treatment. This article illustrated the steps needed to create ideal aesthetics in the maxillary anterior region. Rigorous treatment planning al- lows the implant surgeon, working with the restor- ative dentist, to select location, angulation, and spacingofdentalimplantstoachieveidealaesthet- ics. Treatment planning also dictates the necessity for hard- and soft-tissue grafting, which is often crucial for an ideal aesthetic result. Further, the prosthetic restoration of a dental implant must be ideal to achieve the desired aesthetic result. This article has discussed the importance of a comprehensive and interdisciplinary approach to treatment planning, surgery, and restoration of dental implants in the maxillary anterior region of the mouth._ References 1.
