Soft Tissue Assessment in Screw-Retained Maxillary Complete Denture With Electric Welded Framework Versus Casted

Soft Tissue Changes Assessment in Screw-Retained Maxillary Implant Supported Complete Denture With Electric Welded Metal Framework Versus Casted One (RCT, Split Mouth Design)

comparing the changes in the soft tissue around the implants that will be joined by a metal framework either with electric welding or with the conventional casting method

as joining multiple implants by a metal framework considered a solid solution for edentulous arches , but in the same time the conventional method to weld this metal framework to the implants by casting technique in lab usually involves a several disadvantages eg. cost and time consuming in addition to laboratory errors, Thus , this study aims to find another method to weld the metal framework intraorally by an electric welding device

Inclusion Criteria:

• Ages range from 45 to 65 years old.
• Absence of any medical disorder that could complicate the Surgical phase or affect osseointegration.
• The patients must be completely edentulous.

• Patients with good oral hygiene.
• Complete denture wearer.
• Adequate inter arch space for screw retained prosthesis.
• Absence of any intra-oral pathological condition.

Exclusion Criteria:

• Patients with recent extraction(less than three months).
• Patients with inflamed ridge or candida infection.
• Patients with flappy ridge.
• Parafunctional habits.
