INTRODUCTION: Missing teeth were a problem in the 1950s and 1960s till the real use of titanium dental implants to restore teeth. Scientists tried hard over many years to improve the surface treatment of the dental implant in order to improve the function and longevity of it and to reduce the chances of its failure. New materials and techniques are used to change the surface texture, component, and its surface energy. OBJECTIVES: Evaluation of the delayed placement of ACQUA dental implant versus the conventional type for replacement of maxillary premolar teeth. MATERIALS AND METHODS: Study was conducted on 14 patients. Patients were divided equally into two groups. Group “A" patients received ACQUA Alvium Neodent dental implant while group “B" patients received conventional Alvium dental implants. All Patients had missing maxillary premolars teeth. Patients were between 27- 48 years old. All patients were operated under local anesthesia. The surgical stent was checked for proper seating in the planned site of the dental implant. A full thickness mucoperiosteal flap was performed. Follow-up was done daily for the first week, then weekly for the first month, then monthly for six months. RESULTS: Clinically no edema was shown in all patients. Other clinical parameters were recorded during the follow-up period as the gingival index, implant stability, and presence or absence of infection. Radiographic results showed that there was a significant difference between ACQUA and conventional Alvium dental implant which proved the higher initial stability of ACQUA Alvium Implants compared to conventional ones. Marginal bone height did not show any significant difference between ACQUA implants and conventional implants. CONCLUSIONS: ACQUA dental implant showed more primary stability than conventional Alvium implant. Additionally, ACQUA showed more bone intensity compared to the other type
