Note. This is version 3 of Add Dental Braces. Version 4 has been released may be found at https://huggingface.co/alastandy/Add-Dental-Braces-4 Version 4 is also aviable on civitai at https://civitai.com/models/871278?modelVersionId=1077179

Version 3 vs. Version 4 Skin Texture Improvement:

Version 3 exhibited a tendency to render an airbrushed appearance on facial skin. In contrast, Version 4 incorporated regularization images into its dataset to specifically address this issue.

A/B testing conducted after training demonstrated substantial improvement in this area.

Enhanced Dataset Details:

Version 4 also incorporates enhancements to its dataset to provide more detailed representations of real braces.

A/B testing revealed that Version 4 occasionally introduced subtle features on braces, such as hooks for rubber bands, that were not present in Version 3.

Alternating Band Color Representation:

Version 4 also includes a wider range of examples of braces with alternating band colors in its dataset.

A/B testing demonstrated that Version 4 effectively handled prompts specifying alternating band colors (e.g., “with bands that alternate between blue and green”), outperforming Version 3 in this regard.

Overall Performance Summary:

In summary, Version 4 achieved slightly superior overall results and exhibited fewer anomalies, such as sections of the bracket that should not have been present. Conversely, Version 3 occasionally produced superior bands but at the expense of diminished overall image quality.

Objective: This model aims to add photo-realistic dental braces to subjects' teeth in generated images. The braces should be accurately sized and aligned to fit naturally, while responding to prompts specifying the color of the brackets (e.g., gold or silver) and the color of the bands.

Current Functionality: It is not perfect but version 3 works, and works well most of the time. It works well for male and females.

Training Data: Version 3 of this model was trained on a set of 122 high-resolution (1024 x 1024) photos of real dental braces, using 5124 training steps across 42 epochs. The dataset primarily consists of images showcasing different types of braces and various band colors.

Example Prompts Basic Prompt AddDentalBraces, A 25-year-old adult man with braces on their teeth.

Material-Specific Prompt AddDentalBraces, A 45-year-old middle-aged man with translucent off-white plastic braces.

Custom Bracket and Band Colors AddDentalBraces, An old man with silver metal braces. The brackets have teal-colored bands.

Enhanced Trigger Prompt Including additional mentions of the keyword may enhance response: AddDentalBraces, An old man with AddDentalBraces braces on their teeth. The AddDentalBraces braces are silver-colored metal with teal bands.

(No longer needed in Version 3. Version 3 reliability triggers when the prompt contains "AddDentalBraces" and specifies that the subject has braces on their teeth.)

Tips for Best Results Use specific descriptors for age, gender, and brace materials to improve realism.

Simple prompts, such as

adddentalbraces, A 25-year-old woman with braces on her teeth. consistently yield highly satisfactory results, consistently producing headshot-style photographs. The braces appear most aesthetically pleasing in this close-up style, and the LORA will generally create images in this manner unless the prompt explicitly requests otherwise.

The LORA can also handle more intricate prompts and reliably incorporate the braces, although if these prompts result in full-body shots or distance shots, the quality of the results of the braces added may decrease. The current dataset lacks sufficient examples of braces at a distance, leading to occasional inconsistencies or inaccurate representations. (I am planning to include additional examples of braces at a greater distance in the next version of the dataset to enhance this aspect, but this may require time to obtain or produce images of sufficient quality. I am meticulous about the images in the dataset and firmly believe that the quality of the data is the paramount factor in achieving quality results from the training.)

Stay tuned for updates! User feedback is always welcome, let me know what works and was need improvement.
