The study will assess early osseointegration of dental implant with three different coating materials through secondary implant stability

Dental implants with sandblasted acid itched coating, nano-hydroxyapatite coating, and hyalouronic acid coating will be placed in the posterior maxilla to restore a missing tooth. Implant stability by the use of Ostell will be measured immediately post-operative, 4, 6, and 12 weeks post-operative.

marginal bone loss around the implants will be compared immediately after final restoration delivery and after one year
