Date: October 24, 2023
Clinic Location: Colombo, Sri Lanka
Patient ID: SL-CMB-8902
Laboratory Technician ID: LT-4501
This laboratory report serves as a detailed technical documentation of the dental prosthetic procedures undertaken for Patient SL-CMB-8902. The treatment was conducted within the specialized dental clinic located in the heart of Colombo, Sri Lanka. It is imperative to note that the unique environmental and clinical characteristics of Sri Lanka’s capital city influence both patient demographics and material selection processes. Colombo presents a high demand for restorative dentistry due to a combination of urban lifestyle factors and increasing awareness regarding oral health standards. Consequently, this Dentist has opted for advanced zirconia-based solutions to ensure longevity against local dietary habits, which often include abrasive tea consumption and hard snack preferences common in the region.
The primary objective of this Lab Report is to document the precision, fit, aesthetic integration, and functional verification of a full-arch implant-supported prosthesis. By adhering to rigorous laboratory protocols, we ensure that the final restoration meets the international standards expected by modern practitioners in Sri Lanka Colombo while addressing specific local biomechanical challenges.
The patient presented with severe periodontal breakdown affecting the maxillary arch, resulting in the loss of multiple anterior and posterior teeth. The decision to proceed with an All-on-4® concept was made by the treating dentist to maximize bone utilization, a critical consideration given that many patients in Colombo present with delayed intervention due to economic factors or lack of early dental education.
2.1 Diagnostic Impressions and Scanning
Polyvinyl siloxane (PVS) impressions were taken using dual-phase technique to capture the subgingival margins accurately. These were subsequently digitized using an intraoral scanner for digital workflow integration. The digital model revealed a significant resorption of the alveolar ridge in the anterior maxilla, necessitating precise angulation adjustments on the implant abutments.
In response to the specific demands of patients residing in Sri Lanka Colombo, where humidity levels can affect certain acrylic materials over time, a hybrid material approach was selected. The framework was milled from high-strength Zirconia (5Y-TZP), providing exceptional fracture resistance and biocompatibility. The gingival portion was fabricated using a tissue-colored PMMA reinforced with long-chain polymers to resist staining from local tea stains.

Optimal Compensates for non-parallel implant placement common in atrophic ridges. The fabrication of this prosthesis followed a strict protocol to ensure the integrity of the final product. As a key component of this Lab Report, we detail the steps taken by our team: 4.1 Digital Design (CAD)The dental laboratory technician utilized CAD software to design the prosthesis based on the wax-up provided by the dentist. Special attention was paid to phonetics and esthetics, ensuring that the teeth complemented the patient’s facial structure and lip support, which is crucial for psychological acceptance in social settings within Colombo. 4.2 Milling and SinteringThe Zirconia framework was milled using a 5-axis CNC milling machine. The sintering process was conducted at 1,500°C for four hours to achieve full density. Post-sintering, the dimensions were measured against the digital design using coordinate measuring machines (CMM) to ensure deviations remained below 20 microns. 4.3 Layering and VeneeringThe aesthetic veneering was performed using a layering technique to mimic the natural translucency of human enamel. The shade matching was conducted under D65 standard light sources, which are essential for accurate color perception in the often varied lighting conditions found in many clinics across Sri Lanka Colombo. The prosthesis was returned to the clinic for a clinical try-in. The fit at the implant level was verified using a screw-retained verification jig. The passive fit test confirmed that no pressure points existed on any of the four implants, preventing future mechanical complications such as screw loosening or ceramic fracture. The occlusion was checked in centric relation and during excursive movements. The dentist adjusted the occlusal contacts to ensure equal distribution of force, reducing stress on the bone-implant interface. This is particularly vital for patients in Sri Lanka Colombo who may have a bruxing habit due to local stressors or dietary hardness. The final prosthesis was cemented/screwed into place (depending on the specific implant system used). The patient was provided with comprehensive maintenance instructions, including:
This laboratory report confirms the successful fabrication and delivery of a high-quality, implant-supported prosthesis tailored to the specific needs of a patient in Sri Lanka Colombo. The collaboration between the dentist and the dental laboratory ensured that both functional durability and aesthetic excellence were achieved. By utilizing advanced materials like Zirconia and accounting for local environmental factors, we have provided a solution that is not only clinically sound but also culturally adapted. The data presented in this Lab Report serves as a testament to the high standards of care available in Colombo’s dental sector. It highlights how modern laboratory techniques, when combined with skilled dentistry, can resolve complex full-arch rehabilitation cases effectively. Future follow-ups will monitor the long-term stability of this restoration, contributing to our database on prosthetic outcomes in tropical urban environments. Signed: Dr. A.
