Sinus Lift With Hydroxyapatite Nano Particles Versus Tenting Technique

Schneiderian Membrane Elevation and Augmentation With Hydroxyapatite Nano Particles [ Nano Streams ] Versus Graft Less Tenting Technique With Simultaneous Implant Placement: Randomized Clinical Trial

twenty recruited patients indicated for sinus augmentation and immediate implant placement will be divided into two groups (10 in each of the two groups), to compare bone formation and implant stability after shneiderian membrane elevation and augmentation with Hydroxyapatite Nano particles [Nanostreams] or augmentation with graft less tenting technique with simultaneous implant placement.

Inclusion Criteria:

• Patients with atrophic maxilla and pneumatization of the maxillary sinus with residual bone height at least 5mm of residual ridge as per MISCH criteria
• Both sexes

Exclusion Criteria:

• Sinus pathology
• Heavy smokers more than 20 cigarettes per day
• Patients with systemic disease that may affect normal healing
